74LS192 Synchronous BCD Decade Up/Down Counter IC – DIP-16 Package
The SN54/74LS192 is a UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is a UP/DOWN MODULO-16 Binary Counter. Separate 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 stage without extra logic, thus simplifying multistage counter designs. Individual preset inputs allow the circuits to be used as programmable counters. Both the Parallel Load (PL) and the Master Reset (MR) inputs asynchronously override the clocks. This Product is known as 74192, 74HC192, 74HC192 Decade Up Down Counter IC with Clear, 74XXX series IC, Component, Decade Up Down Counter IC, Decade Up Down Counter IC with Clear
