Overview
The ADM2484EBRWZ, produced by Analog Devices Inc., is an isolated data transceiver designed for high-speed, half- or full-duplex communication on multipoint transmission lines. This device complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E) standards, making it suitable for a variety of industrial and communication applications. The ADM2484EBRWZ employs Analog Devices' iCoupler® technology, which integrates a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. This integration provides robust isolation and protection features, including ±15 kV ESD protection using the human body model (HBM).
