Texas Instruments CD54HC162
The CD54HC160 and CD54HC162 are BCD decade counters. This mode of operation eliminates the output counting spikes that are normally associated with synchronous (ripple-clock) counters. These counters are fully programmable; that is, they can be preset to any number between 0 and 9.| Part No. | CD54HC162 |

Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed by the count-enable (ENP, ENT) inputs and internal gating. A buffered clock (CLK) input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform. As presettin...
