Overview
The SN75176ADE4 is a differential bus transceiver integrated circuit designed by Texas Instruments. It is optimized for bidirectional data communication on multipoint bus-transmission lines, adhering to ANSI Standards EIA/TIA-422-B and ITU Recommendation V.11. 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 particularly suited for applications requiring balanced transmission lines in noisy environments.
