| Description | Synchronous Up/Down 4-Bit Binary Counter |
|
|
This circuit is a synchronous reversible up down counter The 191 is a 4-bit binary 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 output counting spikes normally associated with asynchronous (ripple clock) counters The outputs of the four master-slave...
