Synchronous operation Is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so in structed by the steering logic.

This mode of operation eliminates the output counting spikes normally. The circuit features an asynchronous Parallel Load PL input which overrides counting and loads the data present on the Dn inputs into the flip-flops.

The preset feature allows the ' to be used in programmable dividers. The Count Enable input, the Terminal Count output and the Ripple Clock output make possible a variety of methods of implementing multi-stage counters. In the counting modes, state changes are initiated by the rising edge of the. The preset fea tu re allow s the ' to be used in program m able dividers.

Synchronous operation is provided by having all flip- flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asyn- chronous ripple clock counters. A high at the enable input inhibits counting. Level changes at the enable input should be made only when the clock in- put is high.
