    具有加/減模式控制的同步加/減計數(shù)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;
