The ADM2491E is an isolated data transceiver with 8 kV ESD protection and is suitable for high speed, half- or full-duplex communication on multipoint transmission lines. For halfduplex operation, the transmitter outputs and the receiver inputs share the same transmission line. Transmitter output Pin Y is linked externally to receiver input Pin A, and transmitter output Pin Z to receiver input Pin B. The ADM2491E is designed for balanced transmission lines and complies with ANSI TIA/EIA RS-485-A-1998 and ISO 8482: 1987(E). The device employs Analog Devices, Inc., iCoupler technology to combine a 3-channel isolator, a threestate differential line driver, and a differential input receiver into a single package.
