HD74LS191, Synchronous Up / Down 4-bit Binary Counter
HD74LS191 Synchronous Up / Down 4-bit Binary Counter (single clock line) REJ03D0453 0200 Rev.2.00 Feb.18.2005 Synchronous operation is provided by having all flip-flops clocked simultaneously so that the steering logic.
This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple clock) counters.
The outputs of the four master-slave flip-flops are triggered on a low-to-high-level transition of the clock input if the enable input is high.
