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 KK74HCT21A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) Symbol Parameter Test Conditions VCC V Guaranteed Limit 2 5 °C to -55°C 2.0 2.0 0.8 0.8 4.42 5.42 3.98 0.09 0.09 0.26 -0.1 0.1 4.0 ≤85 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.84 0.1 0.1 0.33 -1.0 1.0 40 ≤125 °C 2.0 2.0 0.8 0.8 4.4 5.4 3.70 0.1 0.1 0.4 -1.0 1.0 160 µA µA µA V V Unit VIH Minimum High-Level Input Voltage Maximum Low -Level Input Voltage Minimum High-Level Output Voltage VIN=VIH or VIL ⎢IOUT⎢ = - 50 µA VIN= VIH or VIL ⎢IOUT⎢ = - 4.0 mA 4.5 5.5 4.5 5.5 4.5 5.5 4.5 4.5 5.5 4.5 5.5 5.5 5.5 VIL V VOH V VOL Maximum Low-Level Output Voltage IIL IIH ICC Maximum Low-Level Input Leakage Current Maximum High-Level Input Leakage Current Maximum Quiescent Supply Current (per Package) Maximum Additional Quiescent Supply Current on input pin VIN= VIH or VIL ⎢IOUT⎢ = 50 µA VIN= VIH or VIL ⎢IOUT⎢ = 4.0 mA VIN= 0 V VIN= VCC VIN=VCC or 0 V IOUT=0 µA VIN=3.4 V any one input, VIN= 0 V or VCC others inputs ICCT 5.5 ≤-55°C 2.9 2 5 °C ÷ -125°C 2.4 mА 3 KK74HCT21A AC ELECTRICAL CHARACTERISTICS (CL=50pF,Input tr=tf=6.0 ns) VCC Symbol Parameter V Guaranteed Limit 2 5 °C to -55°C 27 15 10 ≤85°C ≤125°C Unit tPHL, tPLH tTHL, tTLH CIN Maximum Propagation Delay (Figure 1) Maximum Output Transition Time (Figure 1) Maximum Input Capacitance Power Dissipation Capacitance (Per Gate) 4.5 4.5 5.0 34 19 10 41 22 10 ns ns pF TA=25°C,VCC=5.0 V 50 pF CPD Used to determine the no-load dynamic power consumption: PD=CPDVCC2f+ICCVCC tLH 0.9 0.9 V1 tHL VIH Input 0.1 V1 0.1 GND tPLH 0.9 tPHL VOH 0.9 V1 Output V1 0.1 0.1 0V tTLH V1 = 1.3 V VI = 3.0 V tTHL Figure 1.
