ANALOG DEVICES MAX3462CSA+ Transceiver RS422, RS485, 4.75V-5.25V supply, 1 Driver, NSOIC-8

MAX3462CSA+ is a high-speed differential bus transceiver for RS-485 and RS-422 communications. This is designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards. The part contains one three-state differential line driver and one differential input line receiver. The device operates from a +5V supply and features true fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted. This enables all receiver outputs on a terminated bus to output logic highs when all transmitters are disabled. The device features a 1/4 standard unit load receiver input impedance that allows 128 transceivers on the bus. Driver and receiver propagation delays are guaranteed under 20ns for multidrop, clock distribution applications. Applications include high-speed RS-485 communications, high-speed RS-422 communications, level translators, industrial-control local area networks, profibus applications.
