SN65HVD379DR TI RS-485/RS-422 Transceiver | 8-SOIC | 3.3V, 250kbps, Half-Duplex

Product Overview

The SN65HVD379DR from Texas Instruments is a robust RS-485/RS-422 transceiver designed for balanced communication in industrial and automotive environments. Operating from a 3.3V supply, it supports data rates up to 250 kbps and features a half-duplex architecture. The device is housed in an 8-pin SOIC package and offers enhanced protection against electrostatic discharge (ESD) up to ±16 kV (HBM). Its differential outputs and receiver inputs are optimized for long cable runs and noisy environments, making it ideal for reliable data transmission in harsh conditions.
