Product Summary

The MAX3471EUA is a 1.6μA, 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 2.5V to 5.5V supply voltage guarantees operation over the lifetime of a lithium battery. The MAX3471EUA features true fail-safe operation that guarantees a logic-high receiver output when the receiver inputs are open or shorted. The applications of the MAX3471EUA include: Remote Meter Reading, Battery-Powered Differential Communications, Level Translators.
