Gould AMI - S2350P IC - Transceiver Circuit. Universal Synchronous Receiver/Transmitter (USRT)

The S2350 USRT is a single chip MOS/LSI device that totally replaces the serial-to-parallel and parallel-to- serial conversion logic required to interface a word-parallel controller or data terminal to a bit-serial, synchronous communication network. The USRT consists of separate receiver and transmitter sections with independent clocks, data lines, and status. Common with the transmitter and receiver are word length and parity mode. Data is transmitted and received in a NRZ format at a rate equal to the respective input clock frequency.
