Overview
The SN75176BPSRG4, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. This integrated circuit is tailored for balanced transmission lines and complies with ANSI standards TIA/EIA-422-B and TIA/EIA-485-A, as well as ITU Recommendations V.11 and X.27. It operates from a single 5-V power supply and combines a 3-state differential line driver and a differential input line receiver. The device is suitable for party-line applications due to its wide positive and negative common-mode voltage ranges and minimal loading on the bus when the driver is disabled or VCC = 0.
