description/ordering information
These synchronous, presettable counters feature an internal carry look-ahead for application in high-speed
counting designs. The ’HC161 devices are 4-bit binary counters. 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. This mode of operation eliminates the output
counting spikes that are normally associated with synchronous (ripple-clock) counters. A buffered clock (CLK)
input triggers the four flip-flops on the rising (positive-going) edge of the clock waveform.
