DESCRIPTION
: The IDT54/74AHCT193 is an up/down module-16 binary counter built using advanced CEMOS'●, a dual metal CMOS technology. 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-te-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 si mplifying multistage counter designs. Individual preset inputs allow the circuit to b
