The ’LV163A devices are 4-bit synchronous  
binary counters designed for 2-V to 5.5-V V  
operation.  
CC  
These synchronous, presettable counters feature  
an internal carry look-ahead for application in  
high-speed counting designs. The ’LV163A  
devices are 4-bit binary counters. Synchronous  
NC – No internal connection  
operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with  
each other when instructed by the count-enable (ENP, ENT) inputs and internal gating. This mode of operation  
eliminates the output counting spikes 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.  
These counters are fully programmable; that is, they can be preset to any number between 0 and 9 or 15. As  
presetting is synchronous, setting up a low level at the load input disables the counter and causes the outputs  
to agree with the setup data after the next clock pulse, regardless of the levels of the enable inputs.  
The clear function for the ’LV163A devices is synchronous. A low level at the clear (CLR) input sets all four of  
the flip-flop outputs low after the next low-to-high transition of CLK, regardless of the levels of the enable inputs.  
ThissynchronousclearallowsthecountlengthtobemodifiedeasilybydecodingtheQoutputsforthemaximum  
count desired. The active-low output of the gate used for decoding is connected to CLR to synchronously clear  
the counter to 0000 (LLLL).
