The Maxim ICM7224(LCD) and ICM7225(LED) are high speed 4½ 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 ICM7224 directly drives a non-multiplexed liquid crystal display(LCD). 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 ICM7224 and ICM7225 are available in a 44 lead plastic chip carrier package in addition to the standard 40 lead plastic DIP.
APPLICATIONS
