2 / 5 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 free air temperature range Switching Characteristics over recommended free air operating temperature range Supply Voltage 7V Input Voltage 7V Voltage Applied to a Disabled 3-STATE Output 5.5V Operating Free-Air Temperature Range 0 °C to +70°C Storage Temperature Range −65°C to +150°C Typical θ JA N Package 58.5 °C/W M Package 77.5 °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 0.7 V IOH HIGH Level Output Current −15 mA IOL LOW Level Output Current 24 mA TA Free Air Operating Temperature 0 70 °C Symbol Parameter Test Conditions Min Typ Max Units VIK Input Clamp Voltage VCC = Min, II = −18 mA −1.5 V VOH HIGH Level VCC = 4.5V to 5.5V IOH = −0.4 mA VCC − 2 Output Voltage VCC = Min IOH = −3 mA 2.4 3.2 V IOH = Max 2 VOL LOW Level VCC = Min IOL = 12 mA 0.25 0.4 mA Output Voltage IOL = 24 mA 0.35 0.5 II Input Current @ Maximum Input Voltage VCC = Max, VI = 7V 100 µA IIH HIGH Level Input Current VCC = Max, VI = 2.7V 20 µA IIL LOW Level Input Current VCC = Max, VI = 0.4V −100 µA IOZH HIGH Level 3-STATE Output Current VCC = Max, VO = 2.7V 20 µA IOZL LOW Level 3-STATE Output Current VCC = Max, VO = 0.4V −20 µA IO Output Drive Current VCC = Max, VO = 2.25V −30 −112 mA ICC Supply Current VCC = Max Outputs HIGH 5 10 Outputs LOW 13 22 mA Outputs Disabled 11 19 Symbol Parameter Conditions From (Input) Min Max Units To (Output) tPLH Propagation Delay Time VCC = 4.5V to 5.5V, A or B to Y 2 12 ns LOW-to-HIGH Level Output R1 = R2 = 500Ω, tPHL Propagation Delay Time CL = 50 pF A or B to Y 2 9 ns HIGH-to-LOW Level Output tPZH Output Enable Time to HIGH Level Output G to Y 5 15 ns tPZL Output Enable Time to LOW Level Output G to Y 8 20 ns tPHZ Output Disable Time from HIGH Level Output G to Y 1 10 ns tPLZ Output Disable Time from LOW Level Output G to Y 2 12 ns |
