The device is designed for applications requiring synchronous (parallel transceiver) signal timing. Onchip transient suppression protects the device against destructive IEC 61000 ESD and EFT transients. The device combines a differential driver and a differential receiver, connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. The device features a wide commonmode voltage range mak...
