Integrated Device Technology, Inc. (IDT), was an American semiconductor company headquartered in San Jose, California.

The company designed, manufactured, and marketed low-power, high-performance mixed-signal semiconductor products for the advanced communications, computing, and consumer industries.

The company focused on three major areas: communications infrastructure (wireless and wired), high-performance computing, and advanced power management.

[5] IDT's first product was the first low-power, high-speed CMOS-based 6116 static random-access memory (SRAM) device, released in 1981, followed by the first CMOS FIFO introduced in 1982.

[6] In 1993, IDT entered the PC clock market with a family of devices (CV104, CV105, CV107, and CV109) focusing on desktop computer platforms.

IDT planned to expand its market by producing a suite of PC clock devices that serve next-generation notebook and desktop computing platforms.

The company shifted its initial PC clock family to products serving current-generation desktop, notebook, and server platforms.

This enabled IDT to be one of the few communications IC suppliers to participate in the standards-based Advance Switching initiative spearheaded by Intel.

This transaction included members of the Silicon Optix HQV engineering teams to enable continued delivery of video processing products.

[19] In April 2009, IDT sold its network search engine business to NetLogic Microsystems for approximately $100 million.

[23] In late April of that year, IDT acquired the assets of IKOR, a former subsidiary of iWatt Corporation that manufactures power module VRM products for high-performance computing.

In April, IDT acquired FOX Electronics, a global supplier of frequency control products (FCPs), in an all-cash transaction for approximately $30 million.
