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 IN74HCT27A DC ELECTRICAL CHARACTERISTICS (Voltages Referenced to GND) Symbol Parameter Test Conditions VCC V Guaranteed Limit 25 °C to -55°C 2.0 2.0 0.8 0.8 4.4 5.4 3.98 0.1 0.1 0.26 -0.1 0.1 2.0 ≤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 20 ≤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 40 µA µA µA V V Unit VIH Minimum High-Level Input Voltage Maximum Low -Level Input Voltage Minimum High-Level Output Voltage VOUT≤0.1V or VOUT ≥VCC-0.1V ⎢IOUT⎢≤ 20 µA VOUT≤0.1V or VOUT ≥VCC-0.1V ⎢IOUT⎢≤ 20.
