Description
Presettable 4-bit Binary Up/down Counter
Manufacturer

Datasheet
Presettable 4-Bit Binary UP/DOWN Counter
High-Speed Silicon-Gate CMOS
HC/HCT192. The IN74ACT193 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
Count Down Clock inputs. The direction of counting is determined by
which input is clocked. The outputs change state synchronous with the
LOW-to-HIGH transitions on the clock inputs. This counter may be
preset by entering the desired data on the P0, P1, P2, P3 input. When the
Parallel Load input is taken low the data is loaded independently of either
clock input. This feature allows the counters to be used as devide-by-n by
modifying the count lenght with the preset inputs. In addition the counter
can also be cleared. This is accomplished by inputting a high on the
Master Reset input. All 4 internal stages are set to low independently of
either clock input.Both a Terminal Count Down (TC
Count Up (TC
down counting functions. The TC
pulse when the counter underflows and TC
counter overflows. The counter can be cascaded by connecting the TC
and TC
Clock inputs, respectively, of the next device.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
The IN74ACT193 is identical in pinout to the LS/ALS192,
The counter has two separate clock inputs, a Count Up Clock and
D
outputs of one device to the Count Up Clock and Count Down
