74LS191 | 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 | FAIRCHILD 仙童半导体 |   | |
