Overview

TECHNICAL DATA Synchronous 4 Bit Counters; Binary, Direct Reset This synchronous, presettable counter features an internal carry lookahead for application in high-speed counting designs.
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change conicident with each other when so instructed by the count-enable inputs and internal gating.
This mode of operation eliminates the output counting spikes that 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 wave form.
This counter is fully programmable; that is the outputs ma...
