Optoelectronic Integrated Circuit
TI number: G00099

A research contract from the Air Force resulted in the first optoelectronic integrated circuit. The PEX3002 was introduced at WESCON in 1964.

This item was part of the original S/B Lobby display. The PEX3002 was a multiple switch/chopper which provided a coupling of gallium arsenide and silicon to isolate driver and switch to eliminate bulky transformers. The device was introduced some six or seven years before the industry was ready for its sophistication.
