SN54LS191 | SYNCHRONOUS UP/DOWN COUNTERS WITH DOWN/UP MODE CONTROL 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 | TI 德州仪器 |   | |
SN54LS191 | 具有加/减模式控制的同步加/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; | TI 德州仪器 | | |
