74F192

Up/Down Decade Counter

with Separate Up/Down Clocks

General Description

Features

■ Guaranteed 4000V minimum ESD protection

The 74F192 is an up/down 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 synchronously with the

LOW-to-HIGH transitions on the clock inputs.

Separate Terminal Count Up and Terminal Count Down

outputs are used as the clocks for a subsequent stage

without extra logic, thus simplifying multistage counter

designs. Individual preset inputs allow the circuit to be used

as a programmable counter. Both the Parallel Load (PL)

and the Master Reset (MR) inputs asynchronously override

the clocks.
