ADM2482EBRWZ Datasheet PDF - ADI

●The ADM2482EBRWZ is an Isolated RS-485 Transceiver with integrated transformer driver 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. An on-chip oscillator outputs a pair of square waveforms that drive an external transformer to provide isolated power. The ADM2482E driver has an active high enable and the receiver has an active low enable. The driver output enters a high impedance state when the driver enable signal is low. The receiver output enters a high impedance state when the receiver enable signal is high.
