Synchronous Up / Down 4-bit Binary Counter (single clock line)

Synchronous Up / Down 4-bit Binary Counter (single clock line) 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.

Synchronous 4-Bit Up/Down Counter with Mode Control

General Description The DM74LS191 circuit is a synchronous, reversible, up/down counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change simultaneously when so instructed by the steering logic. This mode of operation eliminates the out
