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 acplished 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 (TCD) and Terminal Count Up (TCU) Outputs are provided to enable cascading of both up and down counting functions. The TCD output produces a negative going pulse when the counter underflows and TCU outputs a pulse when the counter overflows. The counter can be cascaded by connecting the TCU and TCD outputs of one device to the Count Up Clock and Count Down Clock inputs, respectively, of the next device. - TTL/NMOS patible 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 m A ORDERING INFORMATION KK74ACT192N Plastic KK74ACT192D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 16 =VCC PIN 8 = GND ..
