RS-485 transceiver in SOIC-8

The ST485EBDR is a differential bus transceiver IC designed for industrial and automation networks. It enables reliable half-duplex data exchange over twisted-pair wiring in electrically noisy environments.

Fits standard SOIC-8 footprint

This component mounts on a typical eight-lead surface-mount pad pattern and operates from a single supply rail. It frees the designer from adding external driver or receiver chips while providing bus protection for the microcontroller UART.

Replaces discrete driver and receiver pairs

The integrated solution suits new designs that need a compact RS-485 node without the board space or BOM cost of separate line driver and receiver packages. It is not suited for systems that require full-duplex operation or integrated protocol handling.
