Product Introduction

Overview

The ADM489ABRZ is a low-power, differential line transceiver produced by Analog Devices Inc. It is designed for communication on multipoint bus transmission lines and complies with both EIA RS-485 and RS-422 standards. This transceiver is suitable for balanced data transmission and supports full-duplex data transfer. The ADM489ABRZ operates from a single 5 V ± 10% power supply and is ruggedized to handle electrically harsh environments and high RF field strengths without special shielding precautions.
