2 / 4 page www.fairchildsemi.com 2 Absolute Maximum Ratings(Note 1) Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. 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. Recommended Operating Conditions Electrical Characteristics over recommended operating free air temperature range. All typical values are measured at VCC = 5V, TA = 25°C. Switching Characteristics over recommended operating free air temperature range Supply Voltage 7V Input Voltage 7V High Level Output Voltage 7V Operating Free Air Temperature Range 0 °C to +70°C Storage Temperature Range −65°C to +150°C Typical θ JA N Package 83.0 °C/W M Package 114.0 °C/W Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.5 5 5.5 V VIH HIGH Level Input Voltage 2 V VIL LOW Level Input Voltage 0.8 V VOH HIGH Level Output Voltage 5.5 V IOL LOW Level Output Current 24 mA TA Free Air Operating Temperature 0 70 °C Symbol Parameter Conditions Min Typ Max Units VIK Input Clamp Voltage VCC = 4.5V, II = −18 mA −1.5 V IOH HIGH Level Output Current VCC = 4.5V, VOH = 5.5V 100 µA VOL LOW Level VCC = 4.5V IOL = 24 mA 0.35 0.5 V Output Voltage VIH = 2V II Input Current at Maximum VCC = 5.5V, VIH = 7V 0.1 mA Input Voltage IIH HIGH Level Input Current VCC = 5.5V, VIH = 2.7V 20 µA IIL LOW Level Input Current VCC = 5.5V, VIL = 0.4V −0.1 mA ICCH Supply Current with VCC = 5.5V, VI = 0V 0.86 1.6 mA Outputs HIGH ICCL Supply Current with VCC = 5.5V, VI = 4.5V 4.0 7.8 mA Outputs LOW Symbol Parameter Conditions Min Max Units tPLH Propagation Delay Time VCC = 4.5V to 5.5V 10 33 ns LOW-to-HIGH Level Output RL = 500Ω tPHL Propagation Delay Time CL = 50 pF 212 ns HIGH-to-LOW Level Output |
