These synchronous, presettable, 4-bit decade  
and binary counters feature an internal carry  
look-ahead circuitry for application in high-speed  
counting designs. The SN54ALS162B is a 4-bit  
decade counter. The ′ALS161B, ′ALS163B,  
′AS161, and ′AS163 are 4-bit binary counters.  
Synchronous operation is provided by having all  
flip-flops clocked simultaneously so that the  
outputs change coincidentally 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 asynchronous (ripple-clock)  
counters. A buffered clock (CLK) input triggers the  
four flip-flops on the rising (positive-going) edge of  
the clock input waveform.

These counters are fully programmable; they may  
be preset to any number between 0 and 9 or 15.  
Because presetting is synchronous, setting up a  
low level at the load (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.  
NC – No internal connection  
The clear function for the ′ALS161B and ′AS161 is asynchronous. A low level at the clear (CLR) input sets all  
four of the flip-flop outputs low, regardless of the levels of the CLK, LOAD, or enable inputs. The clear function  
for the SN54ALS162B, ′ALS163B, and ′AS163 is synchronous, and a low level at CLR sets all four of the flip-flop  
outputs low after the next clock pulse, 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 and ENT inputs and a ripple-carry (RCO) output are instrumental in accomplishing this  
function. Both ENP and ENT must be high to count, and ENT is fed forward to enable RCO. RCO, thus enabled,  
produces a high-level pulse while the count is maximum (9 or 15 with Q high). The high-level overflow  
A
ripple-carry pulse can be used to enable successive cascaded stages. Transitions at ENP or ENT are allowed,  
regardless of the level of CLK.
