Overview
PRESETTABLE BCD/DECADE 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 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 logic, thus simplifying multistage counter designs.
Individual preset inputs allow the circuits to be used as programmable counters.
Both the Parallel Load (PL...
