74F193
Up/Down Binary Counter with Separate Up/Down Clocks
General Description
The 74F193 is an up/down modulo-16 binary 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 outputs are provided
that are used as the clocks for subsequent stages without
extra logic, thus simplifying multi-stage 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.
