Overview
The SN75176ADG4, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus-transmission lines. This monolithic integrated circuit is optimized for balanced transmission lines and complies with ANSI Standard EIA/TIA-422-B and ITU Recommendation V.11. It combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5-V power supply. The device is suitable for party-line applications due to its wide positive and negative common-mode voltage ranges and is characterized for operation from 0°C to 70°C.
