Overview
The ADM2486BRW, produced by Analog Devices Inc., is a high-speed, half-duplex iCoupler isolated RS-485 transceiver. This integrated component is designed for bidirectional data communication on multipoint bus transmission lines, ensuring galvanic isolation between the logic and bus sides. It combines a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package, making it ideal for applications requiring reliable and isolated data transmission.
