Overview
The SN65LBC176ADRG4 is a differential bus transceiver produced by Texas Instruments. This integrated circuit is designed to meet or exceed the requirements of ANSI Standard TIA/EIA−485−A and ISO 8482:1987(E), making it suitable for high-speed serial and parallel applications. The 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 useful in multipoint transmission on long bus lines in noisy environments due to its robust design and protective features.
