Maxim Integrated (MAX3464CSA+) Transceiver RS422, RS485, 4.75V-5.25V supply

Product Overview
The MAX3464CSA+ is a +5V, fail-safe, 20Mbps, profibus RS485/RS422 transceiver in 8 pin NSOIC package. It is designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11 and X.27 standards. The transceiver complies with the profibus specification providing +2.1V output level with a 54ohm load, 20Mbps data rate and output skew less than 2ns. It contains one three-state differential line driver and one differential input line receiver. The device operate from a +5V supply and has a true fail-safe circuitry which gives 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. It has a 1/4 standard unit load receiver input impedance that allows 128 transceivers on the bus. This device is widely used in high speed RS485 communications, high speed RS422 communications, level translators and profibus applications.
