THVD1429DT TI RS-485/RS-422 Transceiver | 8-SOIC | 3.3V, 12Mbps, Half-Duplex

Product Overview

The THVD1429DT from Texas Instruments is a robust RS-485/RS-422 transceiver designed for industrial communication networks. Operating from a single 3.3V supply, it delivers data rates up to 12 Mbps while maintaining excellent noise immunity and low power consumption. The device features a half-duplex architecture with a differential driver and receiver, integrated protection against electrostatic discharge (ESD) up to ±30 kV (HBM), and a wide common-mode voltage range of -7V to +12V. Housed in a compact 8-SOIC package, the THVD1429DT is ideal for space-constrained applications requiring reliable data transmission over long distances.
