MM74C925 Features

* s Wide supply voltage range: s Guaranteed noise margin: s High noise immunity: 3V to 6V 1V 0.45 VCC (typ.) s High segment sourcing current: 40 mA @ VCC

* 1.6V, VCC = 5V s Internal multiplexing circuitry Design Considerations Segment resistors are desirable to minimize power dissipation and

MM74C925 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.
