| Description | Synchronous 4-Bit Up/Down Counter |
|
|
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 output counting spikes normally associated with asynchronous (ripple clock) counters.
