This synchronous 4-bit binary counter features an internal carry look-ahead for application in high-speed counting designs.
Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs changes coincident with each other when so instructed by the count-enable inputs and internal gating.
This mode is 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 waveform.
This counter is fully p...
