DM74LS293 4-Bit Binary Counter  
General Description  
The ’LS293 counter is electrically and functionally identical  
to the ’LS93. Only the arrangement of the terminals has  
been changed for the ’LS293.  
To use the maximum count length (four-bit binary) of these  
counters, the B input is connected to the Q output. The  
A
input count pulses are applied to input A and the outputs are  
as described in the appropriate function table.  
Each of these monolithic counters contains four master-  
slave flip-flops and additional gating to provide a divide-by-  
two counter and a three-stage binary counter for which the  
count cycle length is divide-by-eight.
