Texas Instruments Incorporated (TI) is an American technology company that designs and manufactures semiconductors and various integrated circuits, which it sells to electronics designers and manufacturers globally.Its headquarters are in Dallas, Texas in the United States. TI is one of the top 10 semiconductor companies worldwide, based on sales volume. The company's focus is on developing analog chips and embedded processors, which account for more than 80% of its revenue. TI also produces TI digital light processing technology and education technology products including calculators, microcontrollers and multi-core processors. To date, TI has more than 45,000 patents worldwide.
Texas Instruments emerged in 1951 after a reorganization of Geophysical Service Incorporated, a company founded in 1930 that manufactured equipment for use in the seismic industry, as well as defense electronics.TI produced the world's first commercial silicon transistor in 1954, and the same year designed and manufactured the first transistor radio. Jack Kilby invented the integrated circuit in 1958 while working at TI's Central Research Labs. TI also invented the hand-held calculator in 1967, and introduced the first single-chip microcontroller in 1970, which combined all the elements of computing onto one piece of silicon.
In 1987, TI invented the digital light processing device (also known as the DLP chip), which serves as the foundation for the company's award-winning DLP technology and DLP Cinema.TI released the popular TI-81 calculator in 1990, which made it a leader in the graphing calculator industry. Its defense business was sold to Raytheon in 1997; this allowed TI to strengthen its focus on digital solutions. After the acquisition of National Semiconductor in 2011, the company had a combined portfolio of nearly 45,000 analog products and customer design tools, making it the world's largest maker of analog technology components.
Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, and Patrick E. Haggerty in 1951. McDermott was one of the original founders of Geophysical Service Inc. (GSI) in 1930. McDermott, Green, and Jonsson were GSI employees who purchased the company in 1941. In November, 1945, Patrick Haggerty was hired as general manager of the Laboratory and Manufacturing (L&M) division, which focused on electronic equipment.By 1951, the L&M division, with its defense contracts, was growing faster than GSI's geophysical division. The company was reorganized and initially renamed General Instruments Inc. Because a firm named General Instrument already existed, the company was renamed Texas Instruments that same year. From 1956 to 1961, Fred Agnich of Dallas, later a Republican member of the Texas House of Representatives, was the Texas Instruments president. Geophysical Service, Inc. became a subsidiary of Texas Instruments. Early in 1988, most of GSI was sold to the Halliburton Company.
Texas Instruments exists to create, make, and market useful products and services to satisfy the needs of its customers throughout the world.— Patrick Haggerty, Texas Instruments Statement of Purpose
In 1930, J. Clarence Karcher and Eugene McDermott founded Geophysical Service, an early provider of seismic exploration services to the petroleum industry. In 1939, the company reorganized as Coronado Corp., an oil company with Geophysical Service Inc (GSI), now as a subsidiary. On December 6, 1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H.B. Peacock purchased GSI. During World War II, GSI expanded their services to include electronics for the U.S. Army, Signal Corps, and U.S. Navy. In 1951, the company changed its name to Texas Instruments, spun off to build seismographs for oil explorationsand with GSI becoming a wholly owned subsidiary of the new company.
An early success story for TI-GSI came in 1965 when GSI was able (under a Top Secret government contract) to monitor the Soviet Union's underground nuclear weapons testing under the ocean in Vela Uniform, a subset of Project Vela, to verify compliance of the Partial Nuclear Test Ban Treaty.
Texas Instruments also continued to manufacture equipment for use in the seismic industry, and GSI continued to provide seismic services. After selling (and repurchasing) GSI, TI finally sold the company to Halliburton in 1988, when GSI ceased to exist as a separate entity.
In early 1952, Texas Instruments purchased a patent license to produce germanium transistors from Western Electric, the manufacturing arm of AT&T, for $25,000, beginning production by the end of the year.[ citation needed ]
On January 1, 1953, Haggerty brought Gordon Teal to the company as a research director. Gordon brought with him his expertise in growing semiconductor crystals. Teal's first assignment was to organize what became TI's Central Research Laboratories, which Teal based on his prior experience at Bell Labs.[ citation needed ]
Among his new hires was Willis Adcock, who joined TI early in 1953. Adcock, who like Teal was a physical chemist, began leading a small research group focused on the task of fabricating "grown-junction, silicon , single-crystal, small-signal transistors. Adcock later became the first TI Principal Fellow.
In January 1954, Morris Tanenbaum at Bell Labs created the first workable silicon transistor.This work was reported in the spring of 1954, at the IRE off-the-record conference on solid-state devices, and was later published in the Journal of Applied Physics. Working independently in April 1954, Gordon Teal at TI created the first commercial silicon transistor and tested it on April 14, 1954. On May 10, 1954, at the Institute of Radio Engineers National Conference on Airborne Electronics in Dayton, Ohio, Teal presented a paper: "Some Recent Developments in Silicon and Germanium Materials and Devices,".
In 1954, Texas Instruments designed and manufactured the first transistor radio. The Regency TR-1 used germanium transistors, as silicon transistors were much more expensive at the time. This was an effort by Haggerty to increase market demand for transistors.
Jack Kilby, an employee at TI's Central Research Labs, invented the integrated circuit in 1958. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, and successfully demonstrated the world's first working integrated circuit on September 12, 1958.Six months later, Robert Noyce of Fairchild Semiconductor (who went on to co-found Intel) independently developed the integrated circuit with integrated interconnect, and is also considered an inventor of the integrated circuit. In 1969, Kilby was awarded the National Medal of Science, and in 1982 he was inducted into the National Inventor's Hall of Fame. Kilby also won the 2000 Nobel Prize in Physics for his part of the invention of the integrated circuit. Noyce's chip, made at Fairchild, was made of silicon, while Kilby's chip was made of germanium. In 2008, TI named its new development laboratory "Kilby Labs" after Jack Kilby.
In 2011, Intel, Samsung, LG, ST-Ericsson, Huawei's HiSilicon Technologies subsidiary, Via Telecom, and three other undisclosed chipmakers licensed the C2C link specification developed by Arteris Inc. and Texas Instruments.
The 7400 series of transistor-transistor logic chips, developed by Texas Instruments in the 1960s, popularized the use of integrated circuits in computer logic. The military-grade version of this was the 5400 series.
Texas Instruments invented the hand-held calculator (a prototype called "Cal Tech") in 1967 and the single-chip microcomputer in 1971, was assigned the first patent on a single-chip microprocessor (invented by Gary Boone) on September 4, 1973.This was disputed by Gilbert Hyatt, formerly of the Micro Computer Company, in August 1990, when he was awarded a patent superseding TI's. This was overturned on June 19, 1996, in favor of TI (note: Intel is usually given credit with Texas Instruments for the almost-simultaneous invention of the microprocessor).
In 1978, Texas Instruments introduced the first single-chip linear predictive coding speech synthesizer.In 1976, TI began a feasibility study of memory-intensive applications for bubble memory then being developed. They soon focused on speech applications. This resulted in the development the TMC0280 one-chip linear predictive coding speech synthesizer, which was the first time a single silicon chip had electronically replicated the human voice. This was used in several TI commercial products beginning with Speak & Spell, which was introduced at the Summer Consumer Electronics Show in June 1978. In 2001, TI left the speech synthesis business, selling it to Sensory Inc. of Santa Clara, California.
In May 1954, Texas Instruments designed and built a prototype of the world's first transistor radio, and, through a partnership with Industrial Development Engineering Associates of Indianapolis, Indiana, the 100% solid-state radio was sold to the public beginning in October of that year.
In the 1960s, company president Pat Haggerty had a team that included Jack Kilby to work on a handheld calculator project. Kilby and two other colleagues created the Cal-Tech, a three-pound battery-powered calculator that could do basic math and fit six-digit numbers on its display. This 4.25 x 6.15 x 1.75 inch calculator's processor would originate the vast majority of Texas Instruments’ revenue.
In 1973, the handheld calculator SR-10 (named after slide rule) and in 1974 the handheld scientific calculator SR-50 were issued by TI. Both had red LED-segments numeric displays. The optical design of the SR-50 is somewhat similar to the HP-35 edited by Hewlett Packard before in early 1972, but buttons for the operations "+", "–", ... are in the right of the number block and the decimal point lies between two neighboring digits.
TI continued to be active in the consumer electronics market through the 1970s and 1980s. Early on, this also included two digital clock models - one for desk and the other a bedside alarm. From this sprang what became the Time Products Division, which made LED watches. Though these LED watches enjoyed early commercial success due to excellent quality, it was short-lived due to poor battery life. LEDs were replaced with LCD watches for a short time, but these could not compete because of styling issues, excessive makes and models, and price points. The watches were manufactured in Dallas and then Lubbock, Texas. Several spin-offs of the Speak & Spell, such as the Speak & Read and Speak & Math, were introduced soon thereafter.
In 1979, TI entered the home computer market with the TI-99/4, a competitor to such entries as the Apple II, Tandy/Radio Shack TRS-80, and the later Atari 400/800 series and Commodore VIC-20. It discontinued the TI-99/4A (1981), the sequel to the 99/4, in late 1983 amid an intense price war waged primarily against Commodore. At the 1983 Winter CES, TI showed models 99/2 and the Compact Computer 40 (CC-40), the latter aimed at professional users. The TI Professional (1983) ultimately joined the ranks of the many unsuccessful DOS and x86-based—but non-compatible—competitors to the IBM PC (the founders of Compaq, an early leader in PC compatibles, all came from TI). The company for years successfully made and sold PC-compatible laptops before withdrawing from the market and selling its product line to Acer in 1998.
TI entered the defense electronics market in 1942 with submarine detection equipment,based on the seismic exploration technology previously developed for the oil industry. The division responsible for these products was known at different times as the Laboratory & Manufacturing Division, the Apparatus Division, the Equipment Group, and the Defense Systems & Electronics Group (DSEG).
During the early 1980s, TI instituted a quality program which included Juran training, as well as promoting statistical process control, Taguchi methods, and Design for Six Sigma. In the late '80s, the company, along with Eastman Kodak and Allied Signal, began involvement with Motorola, institutionalizing Motorola's Six Sigma methodology.Motorola, which originally developed the Six Sigma methodology, began this work in 1982. In 1992, the DSEG division of Texas Instruments' quality-improvement efforts were rewarded by winning the Malcolm Baldrige National Quality Award for manufacturing.
TI developed the AAA-4 infra-red search and track in the late '50s and early '60s for the F-4B Phantomfor passive scanning of jet-engine emissions, but it possessed limited capabilities and was eliminated on F-4Ds and later models.
In 1956, TI began research on infrared technology that led to several line scanner contracts and with the addition of a second scan mirror the invention of the first forward looking infrared (FLIR) in 1963 with production beginning in 1966. In 1972, TI invented the common module FLIRconcept, greatly reducing cost and allowing reuse of common components.
TI went on to produce side-looking radar systems, the first terrain-following radar and surveillance radar systems for both the military and FAA. TI demonstrated the first solid-state radar called Molecular Electronics for Radar Applications. – a joint effort with Raytheon.[ citation needed ]In 1976, TI developed a microwave landing system prototype. In 1984, TI developed the first inverse synthetic aperture radar. The first single-chip gallium arsenide radar module was developed. In 1991, the military microwave integrated circuit program was initiated
In 1961, TI won the guidance and control system contract for the defense suppression AGM-45 Shrike antiradiation missile. This led later to the prime on the high-speed antiradiation missile (AGM-88 HARM) development contract in 1974 and production in 1981.
In 1964, TI began development of the first laser guidance system for precision-guided munitions, leading to the Paveway series of laser-guided bombs (LGBs). The first LGB was the BOLT-117.
In 1969, TI won the Harpoon (missile) Seeker contract. In 1986, TI won the Army FGM-148 Javelin fire-and-forget man portable antitank guided missile in a joint venture with Martin Marietta. In 1991, TI was awarded the contract for the AGM-154 Joint Standoff Weapon.
Because of TI's research and development of military temperature-range silicon transistors and integrated circuits (ICs), TI won contracts for the first IC-based computer for the U.S. Air Force in 1961 (molecular electronic computer)and for ICs for the Minuteman Missile the following year. In 1968, TI developed the data systems for Mariner Program. In 1991 TI won the F-22 Radar and Computer development contract.
As the defense industry consolidated, TI sold its defense business to Raytheon in 1997 for $2.95 billion. The Department of Justice required that Raytheon divest the TI Monolithic Microwave Integrated Circuit (MMIC) operations after closing the transaction.The TI MMIC business accounted for less than $40 million in 1996 revenues, or roughly 2% of the $1.8 billion in total TI defense revenues, and was sold to TriQuint Semiconductor, Inc. Raytheon retained its own existing MMIC capabilities and has the right to license TI's MMIC technology for use in future product applications from TriQuint.
Shortly after Raytheon acquired TI DSEG, Raytheon then acquired Hughes Aircraft from General Motors. Raytheon then owned TI's mercury cadmium telluride detector business and infrared (IR) systems group. In California, it also had Hughes infrared detector and an IR systems business. When again the US government forced Raytheon to divest itself of a duplicate capability, the company kept the TI IR systems business and the Hughes detector business. As a result of these acquisitions, these former arch rivals of TI systems and Hughes detectors work together.
Immediately after acquisition, DSEG was known as Raytheon TI Systems (RTIS).It is now fully integrated into Raytheon and this designation no longer exists.
TI was active in the 1980s, in the area of artificial intelligence. In addition to ongoing developments in speech and signal processing and recognition, it developed and sold the Explorer computer family of Lisp machines. For the Explorer, a special 32-bit Lisp microprocessor was developed, which was used in the Explorer II and the TI MicroExplorer (a Lisp Machine on a NuBus board for the Apple Macintosh). AI application software developed by TI for the Explorer included the gate assignment system for United Airlines, described as "an artificial intelligence program that captures the combined experience and knowledge of a half-dozen United operations experts." In software for the PC, they introduced "Personal Consultant", a rule-based expert system development tool and runtime engine, followed by "Personal Consultant Plus" written in the Lisp-like language from MIT known as Scheme, and the natural language menu system NLMenu.
TI was a major original-equipment manufacturer of sensor, control, protection, and RFID products for the automotive, appliance, aircraft, and other industries. The Sensors & Controls division was headquartered in Attleboro, Massachusetts.
In 2006, Bain Capital LLC, a private equity firm, purchased the Sensors & Controls division for $3.0 billion in cash.The RFID portion of the division remained part of TI, transferring to the Application Specific Products business unit of the Semiconductor division, with the newly formed independent company based in Attleboro taking the name Sensata Technologies.
In 1997, TI sold its software division, along with its main products such as the CA Gen, to Sterling Software, which is now part of Computer Associates. However, TI still owns small pieces of software, such as the software for calculators such as the TI Interactive!.TI also creates a significant amount of target software for its digital signal processors, along with host-based tools for creating DSP applications.
In 2000, a team at TI had a desire to sell Code Composer Studio software to customers via the internet. In response, an employee bought an off-the-shelf program and built an eCommerce platform over the course of one weekend – the result was TI store. During the same year, a separate online integrated circuit sample-ordering system was launched to replace a physical room where orders were received by phone, fax, and email and then fulfilled by hand.
In 2002, the TI store inventory was expanded to include paid evaluation modules (EVMs) and a separate home-grown online evaluation module sample system was launched. This resulted in three separate eCommerce systems for TI: one for paid EVMs, one for sample EVMs, and one for sample integrated circuits.
In 2010, the TI store was completely redesigned using a new online platform. Additionally, sample EVMs were moved into the eStore from the home-grown application.
In 2014, at the TI store, integrated circuit samples were moved into the store from the home-grown application and integrated circuit purchase options were added. These changes combined all evaluation and development modules, integrated circuits, and sample programs into one platform.
In 2015, the TI store increased its maximum order quantity from 99 to 999.
In December 2016, Code Composer Studio v7 was released at no cost, as it included a new licensing model: Technology Software Publicly Available.
On August 6, 1999, TI announced the restatement of its results for parts of 1998 and the first quarter of 1999 after a review by the Securities and Exchange Commission over the timing of charges for a plant closing and writedown.
For the fiscal year 2017, Texas Instruments reported earnings of US$3.682 billion, with an annual revenue of US$14.961 billion, an increase of 11.9% over the previous fiscal cycle. TI shares traded at over $82 per share, and its market capitalization was valued at over US$88.0 billion in October 2018.As of 2018, TI ranked 192nd on the Fortune 500 list of the largest United States corporations by revenue.

Today, TI is made up of four divisions: analog products, embedded processors, digital light processing, and educational technology.
Analog products connect the physical and the digital worlds – turning signals such as sound, pressure, temperature, humidity, and light into digital information to be used by electronic devices – and translating those data back to information to which to interact in the real world. These chips, including data converters and power management and other devices, can extend and optimize battery life, improve accuracy, sense conditions such as humidity and temperature, and much more.
TI's analog integrated-circuit portfolio includes both power-management and signal-chain devices, as well as integrated analog device and application solutions.
TI's subdivision power management includes these product categories:
Texas Instruments maintains several lines of signal-chain product categories.The categories are as follows:
Embedded processors (EP) are the processing brains of electronics that gather inputs from analog chips and perform computational processing to operate a system. EPs can be low power and enable long battery life or energy-efficient products, or they can be high-performance to allow complex analytics systems or systems with high computational throughput, and applications in between. Also included are wireless connectivity products that enable connectivity and help to bring life to the Internet of Things.Texas Instruments Embedded Portfolio Overview is made up of three sub-divisions: Wireless, Microcontrollers, and Processors.
Texas Instruments offers wireless connectivity products, which include these product families:
In addition, TI offers these product families for wireless MCUs:
Texas Instruments also offers a portfolio of microcontrollers, including:
In the past, TI has also sold microcontrollers based on ARM7 (TMS470) and 8051 cores.
In addition to its microcontrollers, TI also produces several multicore processor lines. TI develops specific products that cater to a broad range of Digital Signal Processing applications, such as digital still cameras, cable modems, Voice over IP, streaming media, speech compression and recognition, wireless LAN and gateway products (residential and central office), and RFID.
TI's remaining businesses consisting of DLP products (primarily used in projectors to create high-definition images), calculators and certain custom semiconductors known as application-specific integrated circuits. These businesses, along with royalties, accounted for $1.9 billion of revenue in 2015.
DLP is a trademark under which Texas Instruments sells technology regarding TVs, video projectors, and digital cinema. On February 2, 2000, Philippe Binant, technical manager of Digital Cinema Project at Gaumont in France, realized the first digital cinema projection in Europe with the DLP CINEMA technology developed by TI. DLP technology enables a diverse range of display and advanced light control applications spanning industrial, enterprise, automotive, and consumer market segments.
The ASICs business develops more complex integrated-circuit solutions for clients on a custom basis.
TI has produced educational toys for children, including the Little Professor in 1976 and Dataman in 1977.
TI produces a range of calculators, with the TI-30 being one of the most popular early calculators. TI has also developed a line of graphing calculators, the first being the TI-81, and most popular being the TI-83 Plus (with the TI-84 Plus being an updated equivalent).
Many TI calculators are still sold without graphing capabilities.The TI-30 has been replaced by the TI-30X IIS. Also, some financial calculators are for sale on the TI website.
In 2007, TI released the TI-Nspire family of calculators and computer software that has similar capabilities to the calculators.
Less than 3% of Texas Instruments’ overall revenue comes from calculators, part of the $1.43 billion revenue in the "Other" section in the company's 2018 annual report. The calculators are a lucrative product. For example, estimates have a $15 to $20 cost to produce TI-84 Plus which likely has a profit margin of at least 50%.
Throughout the 1980s, Texas Instruments worked closely with National Council of Teachers of Mathematics (NCTM) to develop a calculator to become the educational standard. In 1986, Connecticut School Board became the first to require a graphing calculator on state-mandated exams. Chicago Public Schools gave a free calculator to every student, beginning in the fourth grade, in 1988. New York required the calculator in 1992 for its Regents exams after first allowing it the previous year. The College Board required calculators on the Advanced Placement tests in 1993 and allowed calculators on the SAT a year later. Texas Instruments provides free services for free to the College Board, which administers AP tests and the SAT, and also has a group called Teachers Teaching for Technology (T3), which educates teachers on how to use its calculators.
In the 1990s, with the advent of TI's graphing calculator series, programming became popular among some students. The TI-8x series of calculators (beginning with the TI-81) came with a built-in BASIC interpreter, through which simple programs could be created. The TI-85 was the first TI calculator to allow assembly programming (via a shell called "ZShell"), and the TI-83 was the first in the series to receive native assembly. While the earlier BASIC programs were relatively simple applications or small games, the modern assembly-based programs rival what one might find on a Game Boy or personal digital assistant.
Around the same time that these programs were first being written, personal web pages were becoming popular (through services such as Angelfire and GeoCities), and programmers began creating websites to host their work, along with tutorials and other calculator-relevant information. This led to the formation of TI calculator webrings and eventually a few large communities, including the now-defunct TI-Files and still-active ticalc.org.
The TI community reached the height of its popularity in the early 2000s, with new websites and programming groups being started almost daily. In fact, the aforementioned community sites were exploding with activity, with close to 100 programs being uploaded daily by users of the sites. Also, a competition existed between both sites to be the top site in the community, which helped increase interest and activity in the community.
One of the common unifying forces that has united the community over the years has been the rather contentious relationship with TI regarding control over its graphing calculators. TI graphing calculators generally fall into two distinct groups - those powered by the Zilog Z80 and those running on the Motorola 68000 series. Both lines of calculators are locked by TI with checks in the hardware and through the signing of software to disable use of custom flash applications and operating systems.
However, users employed the general number field sieve to find the keys and publish them in 2009. TI responded by sending invalid DMCA takedown notices, causing the Texas Instruments signing key controversy. Enthusiasts had already been creating their own operating systems before the finding of the keys, which could be installed with other methods.
TI has the largest market share in the analog semiconductor industry, which has an estimated total addressable market exceeding US$37 billion.[ citation needed ]
On April 4, 2011, Texas Instruments announced that it had agreed to buy National Semiconductor for $6.5 billion in cash. TI paid $25 per share of National Semiconductor stock, which was an 80% premium over the share price of $14.07 as of April 4, 2011 close. The deal made TI the world's largest maker of analog technology components.The companies formally merged on September 23, 2011.
An electronic calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics.
An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs.
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or sometimes up to 8 integrated circuits. The microprocessor is a multipurpose, clock driven, register based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary number system.
Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function and the amplifying function ; it is the same naming convention used in resistor–transistor logic (RTL) and diode–transistor logic (DTL).
Complementary metal–oxide–semiconductor (CMOS), also known as complementary-symmetry metal–oxide–semiconductor (COS-MOS), is a type of MOSFET fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips, and other digital logic circuits. CMOS technology is also used for analog circuits such as image sensors, data converters, RF circuits, and highly integrated transceivers for many types of communication.
Jack St. Clair Kilby was an American electrical engineer who took part in the realization of the first integrated circuit while working at Texas Instruments (TI) in 1958. He was awarded the Nobel Prize in Physics on December 10, 2000. To congratulate him, American President Bill Clinton wrote, "You can take pride in the knowledge that your work will help to improve lives for generations to come."
National Semiconductor was an American semiconductor manufacturer which specialized in analog devices and subsystems, formerly with headquarters in Santa Clara, California, United States. The company produced power management integrated circuits, display drivers, audio and operational amplifiers, communication interface products and data conversion solutions. National's key markets included wireless handsets, displays and a variety of broad electronics markets, including medical, automotive, industrial and test and measurement applications.
Fairchild Semiconductor International, Inc. was an American semiconductor company based in San Jose, California. Founded in 1957 as a division of Fairchild Camera and Instrument, it became a pioneer in the manufacturing of transistors and of integrated circuits. Schlumberger bought the firm in 1979 and sold it to National Semiconductor in 1987; Fairchild was spun off as an independent company again in 1997. In September 2016, Fairchild was acquired by ON Semiconductor.
The history of computing hardware starting at 1960 is marked by the conversion from vacuum tube to solid-state devices such as transistors and then integrated circuit (IC) chips. By 1959, discrete transistors were considered sufficiently reliable and economical that they made further vacuum tube computers uncompetitive. Metal-oxide-semiconductor (MOS) large-scale integration (LSI) technology subsequently led to the development of semiconductor memory in the mid-to-late 1960s and then the microprocessor in the early 1970s. This led to primary computer memory moving away from magnetic-core memory devices to solid-state static and dynamic semiconductor memory, which greatly reduced the cost, size and power consumption of computers. These advances led to the miniaturized personal computer (PC) in the 1970s, starting with home computers and desktop computers, followed by laptops and then mobile computers over the next several decades.
The 7400 series of integrated circuits (ICs) are the most popular logic families. In 1964, Texas Instruments introduced the first members of their ceramic package SN5400 series transistor–transistor logic (TTL) logic chips, later a low-cost plastic package SN7400 series was introduced in 1966 which quickly gained over 50% of the logic chip market, and eventually becoming de facto standardized electronic components. Over the decades, many generations of pin-compatible descendant families evolved to include support for low power CMOS technology, lower supply voltages, and surface mount packages.
In computer engineering, a logic family may refer to one of two related concepts. A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic logical functions, which could be used as "building-blocks" to create systems or as so-called "glue" to interconnect more complex integrated circuits. A "logic family" may also refer to a set of techniques used to implement logic within VLSI integrated circuits such as central processors, memories, or other complex functions. Some such logic families use static techniques to minimize design complexity. Other such logic families, such as domino logic, use clocked dynamic techniques to minimize size, power consumption and delay.
Microchip Technology Inc. is an American publicly-listed corporation that is a manufacturer of microcontroller, mixed-signal, analog and Flash-IP integrated circuits. Its products include microcontrollers, Serial EEPROM devices, Serial SRAM devices, embedded security devices, radio frequency (RF) devices, thermal, power and battery management analog devices, as well as linear, interface and wireless solutions. Examples of these solutions include USB, zigbee, MiWi, LoRa, SIGFOX and Ethernet.
Mark Shepherd Jr. was the chairman and chief executive officer of Texas Instruments. He was in attendance at the demonstration of the integrated circuit by Jack Kilby on September 12, 1958.
A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor's precursor, introduced in 1907. The principle of a field-effect transistor was proposed by Julius Edgar Lilienfeld in 1925.
Dr. Willis Alfred Adcock was a Canadian-American physical chemist, electrical engineer, and university professor who worked on the first atomic bomb and assisted with the invention of the silicon transistor, as well as the integrated circuit. He held several US patents.
Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory. In contrast, with other direct-access data storage media such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory, the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement.
Silicon Systems Inc. (SSi) was an American semiconductor company based in Tustin, California. The company manufactured mixed-signal integrated circuits and semiconductors for telecommunications and data storage.
This article details the history of electronic engineering. Chambers Twentieth Century Dictionary (1972) defines electronics as "The science and technology of the conduction of electricity in a vacuum, a gas, or a semiconductor, and devices based thereon".
The integrated circuit (IC) chip was invented during 1958–1959. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic components in a monolithic semiconductor crystal in 1952. A year later, Harwick Johnson filed a patent for a prototype IC. Between 1953 and 1957, Sidney Darlington and Yasuro Tarui proposed similar chip designs where several transistors could share a common active area, but there was no electrical isolation to separate them from each other.
