ADM2484EBRWZ - ADI Function Overview

The ADM2484EBRWZ is an iCoupler® Isolated RS-485 Transceiver suitable for high speed, half-duplex or full-duplex communication on multipoint transmission lines. For half-duplex operation, the transmitter outputs and 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 device employs the iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver and a differential input receiver. The logic side of the device can be powered with either a 5 or a 3.3V supply, whereas the bus side requires an isolated 3.3V supply. The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention causes excessive power dissipation.
