3 / 5 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: Not more than one output should be shorted at a time, and the duration should not exceed one second. Note 4: 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 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 IOH HIGH Level Output Current −1mA 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=−18 mA −1.2 V VOH HIGH Level VCC = Min, IOH = Max 2.7 3.4 V Output Voltage VIL = Max, VIH = Min VOL LOW Level VCC = Min, IOL =Max 0.5 V Output Voltage VIH = Min, VIL = Max II Input Current @ Max Input Voltage VCC = Max, VI = 5.5V 1 mA IIH HIGH Level Input Current VCC = Max, VI = 2.7V 50 µA IIL LOW Level Input Current VCC = Max, VI = 0.5V −2mA IOS Short Circuit Output Current VCC = Max (Note 3) −40 −100 mA ICC Supply Current VCC Max (Note 4) 67 105 mA RL = 280Ω RL = 280Ω Symbol Parameter From (Input) CL = 15 pF CL = 50 pF Units To (Output) Min Max Min Max tPLH Propagation Delay Time Data to ∑ Even 21 24 ns LOW-to-HIGH Level Output tPHL Propagation Delay Time Data to ∑ Even 18 21 ns HIGH-to-LOW Level Output tPLH Propagation Delay Time Data to ∑ Odd 21 24 ns LOW-to-HIGH Level Output tPHL Propagation Delay Time Data to ∑ Odd 18 21 ns HIGH-to-LOW Level Output |
