MAX3471EUA+

The MAX3471EUA+ is a RS-485/RS-422 half-duplex Differential Transceiver for battery-powered systems. It draws only 1.6μA (typical) supply current from a 3.6V supply with the receiver enabled and the driver disabled. Its wide 2.5 to 5.5V supply voltage guarantees operation over the lifetime of a lithium battery. This device features true fail-safe operation that guarantees a logic-high receiver output when the receiver inputs are open or shorted. This means that the receiver output will be a logic high if all transmitters on a terminated bus are disabled (high impedance). The MAX3471 has a 1/8-unit load input resistance. When driver outputs are enabled and pulled above VCC or below GND, internal circuitry prevents battery back charging.
