4 Digit Counters Single Chip Microcontroller , MM74C925N Arduino Microcontroller Chip

MM74C925N 4-Digit Counters with Multiplexed microcontroller chip

General Description :

The MM74C925, MM74C926, MM74C927 and MM74C928 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.

The MM74C925 is a 4-decade counter and has Latch Enable, Clock and Reset inputs.

The MM74C926 is like the MM74C925 except that it has a display select and a carry-out used for cascading counters.

The carry-out signal goes HIGH at 6000, goes back LOW at 0000.

The MM74C927 is like the MM74C926 except the second most significant digit divides by 6 rather than 10.

Thus, if the clock input frequency is 10 Hz, the display would read tenths of seconds and minutes (i.e., 9:59.9).

The MM74C928 is like the MM74C926 except the most significant digit divides by 2 rather than 10 and the carry-out is

an overflow indicator which is HIGH at 2000, and it goes back LOW only when the counter is reset. Thus, this is a 3½-digit counter.

Features :

■ 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
