provided by having all flip-flops clocked
simultaneously so that the outputs change coincident with each other when instructed by the count-enable
(ENP, ENT) inputs and internal gating. This mode of operation eliminates the output counting spikes normally
associated with synchronous (ripple-clock) counters. A buffered clock (CLK) input triggers the four fl... |
