Synchronous Up/Down Decade Counters(single clock line) Synchronous Up/Down Decade Counters(single clock line) Synchronous operation is provided by having all flip-flops clocked simultaneously so that the output change coincident with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes norm | HitachiHitachi Semiconductor 日立日立公司 | | ||
