But if we are required to use 7474 flipflop, how to do it?
We find that hijacking a thread creates confusion, especially when the topic is a year out of date - http://forum.allaboutcircuits.com/showthread.php?t=18403
Is this related to your other thread? - http://forum.allaboutcircuits.com/showthread.php?t=41203
Look at the internal logic in the data sheet for a counter IC to see how it's done.
Same as an up-counter but use the /Q outputs instead.
On this page from the EDUCYPEDIA you will find links on Digital counters and registers
There are more pages lik that on other digital subjects:
Arithmetic circuits D/A-A/D converters Number systems Codes and decoders Flip flops Technology Counters and registers General overview Technology-CMOS Digital logic Memories Technology-TTL Timers and oscillators
