54F/74F192
Up/Down Decade Counter
with Separate Up/Down Clocks
General Description
The ’F192 is an up/down BCD decade (8421) counter. Sep-
arate Count Up and Count Down Clocks are used, and in
either counting mode the circuits operate synchronously.
The outputs change state synchronously with the LOW-to-
HIGH transitions on the clock inputs.
Separate Terminal Count Up and Terminal Count Down out-
puts are used as the clocks for a subsequent stage without
extra logic, thus simplifying multistage counter designs. Indi-
vidual preset inputs allow the circuit to be used as a pro-
grammable counter. Both the Parallel Load (PL) and the
Master Reset (MR) inputs asynchronously override the
clocks.
