Texas Instruments Inc. (TI) is an American technology company that designs and manufactures semiconductors, which it sells to electronics designers and manufacturers globally. Headquartered in Dallas, Texas, United States, TI is one of the top ten semiconductor companies worldwide, based on sales volume. Texas Instruments's focus is on developing analog chips and embedded processors, which accounts for more than 85% of their revenue.TI also produces TI digital light processing (DLP) technology and education technology products including calculators, microcontrollers and multi-core processors. To date, TI has more than 43,000 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 1950, and designed and manufactured the first transistor radio in 1954. 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 (MCU) 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.

In 1990, TI came out with the popular TI-81 calculator which made them a leader in the graphing calculator industry. In 1997, its defense business was sold to Raytheon, which 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.
