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.
