UP/DOWN COUNTER  
The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the  
SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate  
Count Up and Count Down Clocks are used and in either counting mode the  
circuits operate synchronously. The outputs change state synchronous with  
the LOW-to-HIGH transitions on the clock inputs.  
LOW POWER SCHOTTKY  
Separate Terminal Count Up and Terminal Count Down outputs are  
provided which are used as the clocks for a subsequent stages without extra  
logic, thus simplifying multistage counter designs. Individual preset inputs  
allow the circuits to be used as programmable counters. Both the Parallel  
Load (PL) and the Master Reset (MR) inputs asynchronously override the  
clocks.
