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.

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.

Features

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-

Guaranteed 4000V minimum ESD protection
