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.

LOW POWER SCHOTTKY

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) and the Master Reset (MR) inputs asynchronously override the

clocks.
