/ordering information The ’HC191 devices are 4-bit synchronous, reversible, up/down binary counters.
Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when instructed by the steering logic.
This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters.
