Description
The MM74C925N is a 4-Digit Counters with Multiplexed 7-Segment Output Drivers. These 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 the negative edge of the 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 the 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.
This device is a 4-decade counter and has Latch Enable, Clock, and Reset inputs.
