Overview
The SN75176BPS differential bus transceiver, produced by Texas Instruments, is designed for bidirectional data communication on multipoint bus transmission lines. This device is particularly suited for noisy industrial environments 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 combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5-V power supply. The transceiver features individual driver and receiver enables, wide positive and negative input/output bus voltage ranges, and thermal shutdown protection for line-fault conditions.
