SN54/74LS290  
SN54/74LS293  
DECADE COUNTER;  
4-BIT BINARY COUNTER  
The SN54/74LS290 and SN54/74LS293 are high-speed 4-bit ripple type  
counters partitioned into two sections. Each counter has a divide-by-two sec-  
tion and either a divide-by-five (LS290) or divide-by-eight (LS293) section  
which are triggered by a HIGH-to-LOW transition on the clock inputs. Each  
section can be used separately or tied together (Q to CP)to form BCD,  
Bi-quinary, or Modulo-16 counters. Both of the counters have a 2-input gated  
Master Reset (Clear), and the LS290 also has a 2-input gated Master Set  
(Preset 9).
