ADM4853 RS-485/RS-422 Transceiver

Analog Devices ADM4853 RS-485/RS-422 differential line transceiver is designed for high-speed, half-duplex and full-duplex data communication on multipoint bus transmission lines. The transceiver provides balanced data transmission and complies with EIA Standards RS-485 and RS-422. This half-duplex transceiver shares differential lines and has separate enable inputs for the driver and receiver. The transceiver provides a 1/8-unit load receiver input impedance. This allows up to 256 transceivers on one bus. Only one driver is enabled at a given time.
