ADM2483BRWZ-REEL Datasheet PDF - ADI

GENERAL DESCRIPTION

●The ADM2483differential 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 Analog Devices’ iCoupler technology, the ADM2483 combines a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. The logic side of the device is powered with either a 5 V or 3 V supply, and the bus side uses a 5 V supply only.
