THVD1451D TI RS-485 Transceiver | 8-SOIC | 3.3V, 50Mbps, Half-Duplex

Product Overview

The THVD1451D from Texas Instruments is a robust RS-485 transceiver designed for industrial communication networks. It operates from a single 3.3V supply and supports data rates up to 50 Mbps, making it suitable for high-speed data transmission in harsh environments. The device features a half-duplex architecture and is available in an 8-pin SOIC package. With enhanced ESD protection up to ±30 kV (HBM) and a wide common-mode voltage range of -7V to +12V, the THVD1451D ensures reliable communication in noisy industrial settings.
