This synchronous, presettable, 4-bit binary  
counter has internal carry look-ahead circuitry  
for use in high-speed counting designs.  
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 normally are associated with asynchronous (ripple-clock) counters. However,  
counting spikes can occur on the ripple-carry (RCO) output. A buffered clock (CLK) input triggers the four  
flip-flops on the rising (positive-going) edge of CLK.  
This counter is fully programmable. That is, it can be preset to any number between 0 and 15. Because

to low after the next low-to-high transition of the clock, regardless of the levels of ENP and ENT. 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 the clear input 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. This function is implemented by the ENP and ENT inputs and an RCO output. Both ENP and  
ENT must be high to count, and ENT is fed forward to enable RCO. RCO, thus enabled, produces a  
high-logic-levelpulse while the count is 15 (HHHH). The high-logic-level overflow ripple-carry pulse can be used  
to enable successive cascaded stages. Transitions at ENP or ENT are allowed, regardless of the level of CLK.  
The SN74F163A features a fully independent clock circuit. Changes at ENP, ENT, or LOAD that modify the  
operating mode have no effect on the contents of the counter until clocking occurs. The function of the counter  
(whether enabled, disabled, loading, or counting) is dictated solely by the conditions meeting the setup and hold  
times.
