Overview
The ADM1485ARZ-REEL is a 5 V low power EIA RS-485 transceiver manufactured by Analog Devices Inc. This integrated circuit is designed for high-speed bidirectional data communication on multipoint bus transmission lines, complying with both RS-485 and RS-422 EIA standards. It features a differential line driver and a differential line receiver, both of which can be enabled independently. The transceiver operates from a single 5 V power supply and includes thermal shutdown circuitry to prevent excessive power dissipation during fault conditions.
