________________General Description
The MAX3471 half-duplex transceiver is intended for
lithium battery-powered RS-485/RS-422 applications. It
draws only 1.6A (typical) supply current from a 3.6V
supply with the receiver enabled and the driver dis-
abled. 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 guar-
antees a logic-high receiver output when the receiver
inputs are open or shorted. This means that the receiv-
er output will be a logic high if all transmitters on a ter-
minated 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.
The MAX3471 is available in an 8-pin MAX package.
