Product Introduction

Overview

The ADM3491EARZ-REEL7 from Analog Devices Inc. is a low-power, full-duplex RS422/RS485 transceiver designed for balanced data transmission on multipoint bus transmission lines. This device is suitable for applications requiring high-speed data communication and is optimized for use in EMI-sensitive systems. The transceiver features separate enable inputs for the driver and receiver, allowing for flexible control over the communication lines.
