4-Digit Counters with Multiplexed 7 Segment Output Drivers

The MM74C926 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 external clock. The counters advance on negative edge of clock. A HIGH signal on the Reset input will reset the counter to zero, and reset the carry-out LOW. A LOW signal on the Latch Enable input will latch the number in the counters into the internal output latches. A HIGH signal on Display Select input will select the number in the counter to be displayed; a LOW level signal on the Display Select will select the number in the output latch to be displayed.


  • Wide supply voltage range: 3V to 6V
  • Guaranteed noise margin: 1V
  • High noise immunity: 0.45 VCC (typ.)
  • High segment sourcing current: 40 mA @ VCC 1.6V, VCC = 5V
  • Internal multiplexing circuitry
