3 / 4 page 3 www.fairchildsemi.com 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 (unless otherwise noted) Note 2: All typicals are at VCC = 5V, TA = 25°C. Note 3: ICC is measured with all inputs grounded and all outputs OPEN. Switching Characteristics at VCC = 5V and TA = 25°C Supply Voltage 7V Input Voltage 5.5V Output Voltage 30V Operating Free Air Temperature Range 0 °C to +70°C Storage Temperature Range −65°C to +150°C Symbol Parameter Min Nom Max Units VCC Supply Voltage 4.75 5 5.25 V VIH HIGH Level Input Voltage 2 V VIL LOW Level Input Voltage 0.8 V VOH HIGH Level Output Voltage 30 V IOL LOW Level Output Current 20 mA TA Free Air Operating Temperature 0 70 °C Symbol Parameter Conditions Min Typ Max Units (Note 2) VI Input Clamp Voltage VCC = Min, II = −12 mA −1.5 V ICEX HIGH Level VCC = Min, VO = 30V 250 µA Output Current VIL = Max, VIH = Min VOL LOW Level VCC = Min, IOL = Max 0.2 0.4 Output Voltage VIH = Min, VIL = Max V IOL = 80 mA 0.5 0.9 VCC = Min II Input Current @ Max Input Voltage VCC = Max, VI = 5.5V 1 mA IIH HIGH Level Input Current VCC = Max, VI = 2.4V 40 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −1.6 mA ICC Supply Current VCC = Max (Note 3) 43 70 mA Symbol Parameter Conditions Min Max Units tPLH Propagation Delay Time CL = 15 pF 49.5 ns LOW-to-HIGH Level Output RL = 100Ω tPHL Propagation Delay Time 49.5 ns HIGH-to-LOW Level Output |
