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 5.5V 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 −1 mA IOL LOW Level Output Current 20 mA TA Free Air Operating Temperature 70 °C 2 V 0 Electrical Characteristics over recommended operating free air temperature (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 LOW Level VCC = Min, IOL = Max Output Voltage VIL = Max II Input Current @ Max Input Voltage IIH HIGH Level Input Current IIL VOL Min 2.7 Typ (Note 2) Max Units −1.2 V 3.4 V 0.5 V VCC = Max, VI = 5.5V 1 mA VCC = Max, VI = 2.7V 50 µA LOW Level Input Current VCC = Max, VI = 0.5V −2 mA IOS Short Circuit Output Current VCC = Max (Note 3) −100 mA ICCH Supply Current with Outputs HIGH VCC = Max 18 32 mA ICCL Supply Current with Outputs LOW VCC = Max 38 68 mA −40 Note 2: All typicals are at VCC = 5V, TA = 25°C.
