description  
SN54ALS193A . . . FK PACKAGE  
(TOP VIEW)  
The ’ALS193A are synchronous, reversible, 4-bit  
up/down binary counters. Synchronous counting  
operation is provided by having all flip-flops  
clocked simultaneously so that the outputs  
change coincident with each other when  
instructed by the steering logic. This mode of  
operation eliminates the output counting spikes  
normally associated with asynchronous (ripple-  
clock) counters.

The outputs of the four flip-flops are triggered on  
a low-to-high-level transition of either count/clock  
(UP or DOWN) input. The direction of the count is  
determined by which count input is pulsed while  
the other count input is high.  
NC – No internal connection  
All four counters are fully programmable; that is, each output may be preset to either level by placing a low on  
the load (LOAD) input and entering the desired data at the data inputs. The output changes to agree with the  
data inputs independently of the count pulses. This feature allows the counters to be used as modulo-N dividers  
by simply modifying the count length with the preset inputs.  
A high level applied to the clear (CLR) input forces all outputs to the low level. The clear function is independent  
of the count and LOAD inputs. The UP, DOWN, and LOAD inputs are buffered to lower the drive requirement,  
which significantly reduces the loading on, or current required by, clock drivers, etc., for long parallel words.  
These counters are designed to be cascaded without the need for external circuitry. The borrow (BO) output  
produces a low-level pulse while the count is zero (all Q outputs low) and the DOWN input is low. Similarily, the  
carry (CO) output produces a low-level pulse while the count is 9 or 15 (all Q outputs high) and the UP input  
is low. The counters can then be easily cascaded by feeding BO and CO to the count-down and count-up inputs,  
respectively, of the succeeding counter.  
The SN54ALS193A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ALS193A is characterized for operation from 0°C to 70°C.
