LCD DRVR 4.5DIGIT 5V 44-Pin PLCC T/R

The ICM7225(LED) are high speed 41/2 digit counters, featuring segment decoders, leading zero blanking, store and reset inputs, and a carry output that allows cascading of 8 or more digits.The ICM7225 has 29 constant current outputs for driving a non-multiplexed common anode LED display. These counters operate with inputs from DC to 25MHz while using only 10µA of supply current. A Schmitt trigger on the count input ensures reliable operation in noisy environments and in applications with slowly varying inputs.The ICM7225 are available in a 44 lead plastic chip carrier package in addition to the standard 40 lead plastic DIP.
