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) and the Master Reset (MR) inputs asynchronously override the
clocks.
Low Power . . . 95 mW Typical Dissipation
High Speed . . . 40 MHz Typical Count Frequency
