SN65HVD1471D TI RS-485 Transceiver | 8-SOIC | 3.3V, 50Mbps, Half-Duplex

Product Overview

The SN65HVD1471D from Texas Instruments is a robust half-duplex RS-485 transceiver designed for industrial communication networks. Operating from a 3.3V supply, it delivers data rates up to 50 Mbps while maintaining low power consumption. The device features a 1/8 unit load, allowing up to 256 nodes on a single bus. Its extended common-mode voltage range of -7V to +12V and enhanced ESD protection (16 kV HBM) ensure reliable operation in harsh environments. The 8-SOIC package enables compact PCB designs.
