SN65HVD37D Description

The SN65HVD37D from Texas Instruments is a high-performance RS-422/RS-485 transceiver designed for robust differential communication in industrial and automotive environments. Housed in a 14-pin SOIC package, this full-duplex transceiver integrates one driver and one receiver, supporting data rates up to 20 Mbps. Operating within a 3V to 3.6V supply range, it ensures low-power operation while maintaining compliance with ROHS3 and REACH environmental standards. Its 60 mV receiver hysteresis enhances noise immunity, making it ideal for electrically noisy applications. The device is surface-mount compatible and rated for unlimited moisture sensitivity (MSL 1), ensuring reliability in harsh conditions.
