SN65HVD1477DR TI RS-485 Transceiver | 8-SOIC | 3.3V, 50Mbps, Half-Duplex

Product Overview

The SN65HVD1477DR from Texas Instruments is a robust RS-485/RS-422 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 half-duplex architecture with a differential driver and receiver, making it ideal for balanced transmission lines. Its extended common-mode range and fail-safe receiver ensure reliable operation in harsh environments. The 8-SOIC package enables compact PCB designs for space-constrained applications.
