The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. 7V Input Voltage 7V 0°C to +70°C Operating Free Air Temperature Range −65°C to +150°C Storage Temperature Range Recommended Operating Conditions Symbol Parameter Min Nom Max 4.75 5 5.25 Units VCC Supply Voltage VIH HIGH Level Input Voltage V VIL LOW Level Input Voltage 0.8 V IOH HIGH Level Output Current −0.4 mA IOL LOW Level Output Current 8 mA TA Free Air Operating Temperature 70 °C 2 V 0 Electrical Characteristics over recommended operating free air temperature range (unless otherwise noted) Symbol Parameter Conditions VI Input Clamp Voltage VCC = Min, II = −18 mA VOH HIGH Level VCC = Min, IOH = Max, Output Voltage VIH = Min VOL LOW Level VCC = Min, IOL = Max, Output Voltage VIL = Max Min Typ (Note 2) 2.7 Max Units −1.5 V 3.4 IOL = 4 mA, VCC = Min V 0.35 0.5 0.25 0.4 V II Input Current @ Max Input Voltage VCC = Max, VI = 7V 0.1 IIH HIGH Level Input Current VCC = Max, VI = 2.7V 20 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −0.36 mA IOS Short Circuit Output Current VCC = Max (Note 3) −100 mA ICCH Supply Current with Outputs HIGH VCC = Max 2.4 4.8 mA ICCL Supply Current with Outputs LOW VCC = Max 4.4 8.8 mA −20 mA Switching Characteristics at VCC = 5V and TA = 25°C RL = 2 kΩ Symbol tPLH CL = 15 pF Parameter Propagation Delay Time LOW-to-HIGH Level Output tPHL Propagation Delay Time HIGH-to-LOW Level Output CL = 50 pF Max Min Max 4 13 6 18 ns 3 11 5 18 ns Note 2: All typicals are at VCC = 5V, TA = 25°C.
