Overview
The SN65176BDR, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. It is specifically engineered to meet or exceed the requirements of ANSI standards TIA/EIA-422-B and TIA/EIA-485-A, as well as ITU Recommendations V.11 and X.27. This device combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5-V power supply. The SN65176BDR is housed in an 8-pin SOIC package and is suitable for a wide range of industrial and commercial applications due to its robust operating temperature range of -40°C to 105°C.
