74C925规格书详情
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.
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
