HD74LS190 | 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 |   | |
HD74LS190 | Synchronous Up / Down Decade Counter (signal clock line) 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 asynchronous (ripple clock) counte | RENESAS 瑞萨 | | |
