ADM2481 Datasheet Isolated Rs-485 Transceiver

Manufacturer: Analog Devices

Overview: Data Sheet ADM2481 Half-Duplex, iCoupler Isolated RS-485 Transceiver.

General Description

The ADM2481 differential bus transceiver is an integrated, galvanically isolated component designed for bidirectional data communication on balanced, multipoint bus transmission lines.

It complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).

Using iCoupler® technology from Analog Devices, Inc., the ADM2481 combines a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package.
