TheSN54/74LS390andSN54/74LS393eachcontainapairofhigh-speed  
4-stage ripple counters. Each half of the LS390 is partitioned into a  
divide-by-two section and a divide-by five section, with a separate clock input  
for each section. The two sections can be connected to count in the 8.4.2.1  
BCD codeortheycancountinabiquinarysequencetoprovideasquarewave  
(50% duty cycle) at the final output.  
BINARY COUNTER  
LOW POWER SCHOTTKY  
Each half of the LS393 operates as a Modulo-16 binary divider, with the last  
three stages triggered in a ripple fashion. In both the LS390 and the LS393,  
the flip-flops are triggered by a HIGH-to-LOW transition of their CP inputs.  
Each half of each circuit type has a Master Reset input which responds to a  
HIGH signal by forcing all four outputs to the LOW state.
