TECHNICAL DATA

KK74ACT192

Presettable BCD/Decade UP/DOWN Counter

High-Speed Silicon-Gate CMOS

The KK74ACT192 is identical in pinout to the LS/ALS192,

HC/HCT192. The KK74ACT192 may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

The counter has two separate clock inputs, a Count Up Clock and

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_D) and Terminal Count Up (TC_U) Outputs are provided to

enable cascading of both up and down counting functions. The TC_D

output produces a negative going pulse when the counter underflows

and TC_Uoutputs a pulse when the counter overflows. The counter can

be cascaded by connecting the TC_Uand TC_Doutputs of one device to

the Count Up Clock and Count Down Clock inputs, respectively, of

the next device.
