Overview
The SN65LBC175 is a monolithic, quadruple, differential line receiver designed by Texas Instruments. It is optimized to meet the requirements of the EIA standards RS-422-A, RS-423-A, RS-485, and CCITT Recommendation V.11. This device is particularly suited for balanced multipoint bus transmission in noisy environments and supports data rates up to and exceeding 10 million bits per second. The SN65LBC175 is built using TI's proprietary LinBiCMOS™ technology, which ensures low power consumption, high switching speeds, and robustness.
