SN54/74LS192 SN54/74LS193 PRESETTABLE BCD/DECADE UP/DOWN COUNTER PRESETTABLE 4-BIT BINARY PRESETTABLE BCD / DECADE UP/DOWN COUNTER UP/ DOWN COUNTER PRESETTABLE 4-BIT BINARY UP/ DOWN COUNTER The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate LOW POWER SCHOTTKY Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitions on the clock inputs. Separate Terminal Count Up and Terminal Count Down outputs are provided which are used as the clocks for a subsequent stages without extra J SUFFIX logic, thus simplifying multistage counter designs. Individual preset inputs CERAMIC allow the circuits to be used as programmable counters. Both the Parallel CASE 620-09 16 Load (PL) and the Master Reset (MR) inputs asynchronously override the 1 clocks.
