TECHNICAL DATA KK74AC193 Presettable 4-Bit Binary UP/DOWN Counter High-Speed Silicon-Gate CMOS The KK74AC193 is identical in pinout to the LS/ALS193, HC/HCT193. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. 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 (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. • Outputs Directly Interface to CMOS, NMOS, and TTL • Operating Voltage Range: 2.0 to 6.0 V • Low Input Current: 1.0 µA; 0.1 µA @ 25°C • High Noise Immunity Characteristic of CMOS Devices • Outputs Source/Sink 24 mA ORDERING INFORMATION KK74AC193N Plastic KK74AC193D SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM PIN 16 =VCC PIN 8 = GND 1 KK74AC193 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Seconds (Plastic DIP or SOIC Package) Value -0.5 to +7.0 -0.5 to VCC +0.5 -0.5 to VCC +0.5 ±20 ±50 ±50 750 500 -65 to +150 260 Unit V V V mA mA mA mW °C °C Maximum Ratings are those values beyond which damage to the device may occur.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. 2 KK74AC193 DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) VCC Symbol VIH Parameter Minimum High-Level Input Voltage Maximum Low -Level Input Voltage Minimum High-Level Output Voltage Test Conditions VOUT=0.1 V or VCC-0.1 V V 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 3.0 4.5 5.5 5.5 5.5 5.5 5.5 8.0 Guaranteed Limits 2 5 °C 2.1 3.15 3.85 0.9 1.35 1.65 2.9 4.4 5.4 2.56 3.86 4.86 0.1 0.1 0.1 0.36 0.36 0.36 ±0.1 -40°C to 8 5 °C 2.1 3.15 3.85 0.9 1.35 1.65 2.9 4.4 5.4 2.46 3.76 4.76 0.1 0.1 0.1 0.44 0.44 0.44 ±1.0 75 -75 80 µA mA mA µA V Unit V VIL VOUT=0.1 V or VCC-0.1 V V VOH IOUT ≤ -50 µA V VIN=VIH or VIL IOH=-12 mA IOH=-24 mA IOH=-24 mA VOL Maximum Low-Level Output Voltage IOUT ≤ 50 µA * * VIN=VIH or VIL IOL=12 mA IOL=24 mA IOL=24 mA VIN=VCC or GND VOLD=1.65 V Max VOHD=3.85 V Min VIN=VCC or GND IIN IOLD IOHD ICC Maximum Input Leakage Current +Minimum Dynamic Output Current +Minimum Dynamic Output Current Maximum Quiescent Supply Current (per Package) * All outputs loaded; thresholds on input associated with output under test. +Maximum test duration 2.0 ms, one output loaded at a time.
