Overview
The SN65LBC175AD is a quadruple differential line receiver with 3-state outputs, designed by Texas Instruments for applications requiring high-speed multipoint data transmission. This device is optimized for TIA/EIA-485 (RS-485), TIA/EIA-422 (RS-422), and ISO 8482 (Euro RS-485) standards. It is part of the SN65LBC175A series, characterized for operation over the industrial temperature range of −40°C to 85°C. The SN65LBC175AD is built using TI's proprietary LinBiCMOS™ technology, which ensures low power consumption, high switching speeds, and robust performance in harsh environments.
