Overview
The SN65176BDRE4, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. This device is compliant 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 is suitable for balanced transmission lines and is particularly useful in noisy environments and party-line applications.
