Synchronous 4-Bit Counters

These synchronous, presettable counters feature an internal carry look-ahead for application in high-

speed counting designs. The 161 and 163 are 4-bit binary counters. The carry output is decoded

by means of a NOR gate, thus preventing spikes during the normal counting mode of operation.

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 inputs and internal gating.

This mode of operation eliminates the output counting spikes which are normally associated with

asynchronous (ripple clock) counters. A buffered clock input triggers the four flip-flops on the rising

(positive-going) edge of the clock input waveform.
