Description:
Synchronous up/down decade/4-bit binary counter(single clock line).
The HD74HC190 and HD74HC191 are synchronous, reverside up/down counters.
The HD74HC190 is a 4-bit decade counter and the HD74HC191 is a 4-bit binary counter.
Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each oth
