4-Digit Counters with Multiplexed 7-Segment Output Drivers

General Description\nThese CMOS counters consist of a 4-digit counter, an internal output latch, NPN output sourcing drivers for a 7-segment display, and an internal multiplexing circuitry with four multiplexing outputs. The multiplexing circuit has its own free-running oscillator, and requires no e Wide supply voltage range 3V to 6V\nGuaranteed noise margin 1V\nHigh noise immunity 0.45 VCC(typ.)\nHigh segment sourcing current 40 mA\n???????????????????????? @VCCb1.6V, VCCe5V\nInternal multiplexing circuitry;
