54LS192DM74LS192 UpDown Decade Counter

with Separate UpDown Clocks

General Description

The ’LS192 is an updown BCD decade (8421) 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

Separate Terminal Count Up and Terminal Count Down out-

puts are provided which are used as the clocks for a subse-

quent stage 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
