Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. †Derating − SOIC Packages: – 7 mW/°C from 65° to 125°C TSSOP Package: − 6.1 mW/°C from 65° to 125°C RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit VCC DC Supply Voltage 4.5 5.5 V Vin DC Input Voltage 0 5.5 V Vout DC Output Voltage VCC = 0 High or Low State 0 0 5.5 VCC V TA Operating Temperature −55 + 125 °C tr, tf Input Rise and Fall Time VCC =5.0 V ± 0.5 V 0 20 ns/V DC ELECTRICAL CHARACTERISTICS Symbol Parameter Test Conditions VCC V TA = 25°C TA = − 55 to 125°C Unit Min Typ Max Min Max VIH Minimum High−Level Input Voltage 4.5 to 5.5 2.0 2.0 V VIL Maximum Low−Level Input Voltage 4.5 to 5.5 0.8 0.8 V VOH Minimum High−Level Output Voltage Vin = VIH or VIL IOH = −50 mA 4.5 4.4 4.5 4.4 V IOH = −8 mA 4.5 3.94 3.80 VOL Maximum Low−Level Output Voltage Vin = VIH or VIL IOL = 50 mA 4.5 0.0 0.1 0.1 V IOL = 8 mA 4.5 0.36 0.44 Iin Maximum Input Leakage Current Vin = 5.5 V or GND 0 to 5.5 ±0.1 ±1.0 mA ICC Maximum Quiescent Supply Current Vin = VCC or GND 5.5 2.0 20.0 mA ICCT Quiescent Supply Current Per Input: VIN = 3.4 V Other Input: VCC or GND 5.5 1.35 1.50 mA IOPD Output Leakage Current VOUT = 5.5 V 0 0.5 5.0 mA This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance cir- cuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v 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. |
