The MAX3471 half-duplex transceiver is intended for
lithium battery-powered RS-485/RS-422 applications. 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.
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 backcharging.
The MAX3471 is available in an 8-pin μMAX package.
