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 is 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. The company holds 45,000 patents worldwide as of 2016.
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.
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
Silicon transistor has higher melting temperature and greater reactivity, silicon was much more difficult to work with than germanium, but it offered major prospects for better performance, especially in switching applications.
Germanium transistors make leaky switches; substantial leakage currents can flow when these devices are supposedly in their off state. Silicon transistors have far less leakage. In 1954 Texas Instruments produced the first commercially available silicon junction transistors and quickly dominated this new market—especially for military applications, in which their high cost was of little concern.
