Overview
The SN65LBC176DRG4 is a differential bus transceiver produced by Texas Instruments. This device is designed to meet the requirements of ANSI Standard TIA/EIA-485 (RS-485) and ISO 8482:1987(E), making it suitable for high-speed, low-power applications. It combines a 3-state, differential line driver and a differential input line receiver, both operating from a single 5-V power supply. The device is optimized for multipoint transmission on long bus lines in noisy environments and features high-speed, low-power LinBiCMOS™ circuitry.
