Overview
The SN65ALS176DG4, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. This device combines a 3-state, differential line driver and a differential input line receiver, both operating from a single 5-V power supply. It is compliant with TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27, making it suitable for various industrial and communication applications.
