The device targets such applications as thermometers, digital clocks, and instrumentation readouts. The unit can drive up to 46 segments of nonmultiplexed LCDs and can be cascaded to increase this number. A serial interface makes it easy to integrate the driver into microprocessor systems. The unit consumes a mere 5 A and provides brightness stability over a wide temperature range. Power-supply input ranges from 3 to 5.5 V.
