SN65HVD1781D TI RS-485 Transceiver | 8-SOIC | 3.3V/5V, 250kbps, Half-Duplex

Product Overview

The SN65HVD1781D from Texas Instruments is a robust RS-485/RS-422 transceiver designed for industrial applications requiring reliable data transmission over long distances. It operates from a single 3.3V or 5V supply and supports data rates up to 250 kbps. The device features a half-duplex architecture with a differential output and input, providing excellent noise immunity and common-mode voltage range. Housed in an 8-pin SOIC package, it is ideal for space-constrained designs.
