74F193
Up/Down Binary Counter with Separate Up/Down Clocks
General Description
The ’F193 is an up/down modulo-16 binary counter. Sepa-
rate Count Up and Count Down Clocks are used, and in ei-
ther 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 pre-
set 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.
