DM74LS191 | Synchronous 4-Bit Up/Down Counter with Mode Control General Description 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 out | FairchildFairchild Semiconductor 仙童半导体飞兆/仙童半导体公司 |   | |
