description/ordering information  
This synchronous, presettable counter features an  
internal carry look-ahead for application in  
high-speed counting designs. The SN74HC163 is a  
4-bit binary counter. Synchronous operation is  
provided by having all flip-flops clocked  
ENP  
GND  
ENT  
LOAD  
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.  
This counter is fully programmable; that is, it 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 SN74HC163 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.  
This synchronous clear allows the count length to be modified easily by decoding the Q outputs for the maximum  
count desired. The active-low output of the gate used for decoding is connected to CLR to synchronously clear  
the counter to 0000 (LLLL).  
The carry look-ahead circuitry provides for cascading counters for n-bit synchronous applications without  
additional gating. ENP, ENT, and a ripple-carry output (RCO) are instrumental in accomplishing this function.  
Both ENP and ENT must be high to count, and ENT is fed forward to enable RCO. Enabling RCO produces a  
high-level pulse while the count is maximum (9 or 15 with Q high). This high-level overflow ripple-carry pulse  
A
can be used to enable successive cascaded stages. Transitions at ENP or ENT are allowed, regardless of the  
level of CLK.
