The 74HC191 is an asynchronously presettable 4-bit binary up/down counter.
It contains four master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operation.
Asynchronous parallel load capability permits the counter to be preset to any desired value.
