54F 74F192 Up Down Decade Counter with Separate Up Down Clocks
November 1994
54F 74F192
Up Down Decade Counter
with Separate Up Down Clocks
General Description
The 鈥橣192 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
