SN74LS191

具有加/减模式控制的同步 4 位加/减计数器

The '190, 'LS190, '191, and 'LS191 are synchronous, reversible up/down counters having a complexity of 58 equivalent gates. The '191 and 'LS191 are 4-bit binary counters and the '190 and 'LS190 are BCD counters. Synchronous operation is provided by having all flip-flops clocked simultaneously so tha • Counts 8-4-2-1 BCD or Binary• Single Down/Up Count Control Line• Count Enable Control Input• Ripple Clock Output for Cascading• Asynchronously Presettable with Load Control• Parallel Outputs• Cascadable for n-Bit Applications;
