The MAX3491AEASD+ is a full-duplex transceiver supporting both RS-422 and RS-485 protocols, with a single driver and single receiver on a 14-SOIC footprint. The 10 mV receiver hysteresis filters out noise on long cable runs, reducing the chance of false edge transitions in electrically noisy environments.
