ADM2487EBRWZ Datasheet PDF - ADI

●The ADM2487EBRWZ is a 2.5kV Isolated Data Transceiver with ±15kV ESD protection and is 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 Analog Devices Inc., iCoupler® technology to combine a 3-channel isolator, a 3-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 logic side of the device is powered with either 5 or 3.3V supply and the bus side are powered with an isolated 3.3V supply. The 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.
