National Semiconductor MM74C928

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 3 -digit counter Features Y Y Y Y Wide supply voltage range Guaranteed noise margin High noise immunity High segment sourcing current Internal multiplexing circuitry 3V to 6V 1V 0 45 VCC (typ ) 40 mA VCC b 1 6V VCC e 5V Y Design Considerations Segment resistors are desirable to minimize power dissipation and chip heating The DS75492 serves as a good digit driver when...
