ISO1432DWR TI RS-485 Transceiver | 16-SOIC | 3.3V, 500kbps, Half-Duplex

Product Overview

The ISO1432DWR from Texas Instruments is a robust, isolated RS-485 transceiver designed for reliable data communication in harsh industrial environments. It integrates a galvanic isolation barrier of up to 5 kV RMS, ensuring signal integrity and safety in systems with large ground potential differences. The device operates from a single 3.3V supply and supports data rates up to 500 kbps, making it suitable for long-distance, low-power communication. Housed in a compact 16-SOIC package, the ISO1432DWR simplifies board design while providing high electromagnetic immunity.
