3 / 7 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. All typical values are measured at VCC = 5V, TA = 25°C. Supply Voltage 7V Input Voltage 7V Voltage Applied to Disabled 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 73.0 °C/W M Package 102.0 °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 IOH HIGH Level Output Current −2.6 mA 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 VOH HIGH Level VCC = 4.5V IOH = −2.6 mA 2.4 3.3 V Output Voltage IOH = −0.4 mA VCC − 2V VOL LOW Level VCC = 4.5V IOL = 12 mA 0.25 0.4 V Output Voltage IOL = 24 mA 0.35 0.5 V 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 IO Output Drive Current VCC = 5.5V, VO = 2.25V −30 −112 mA IOZH OFF-State Output Current VCC = 5.5V, 20 µA HIGH Level Voltage Applied VO = 2.7V IOZL OFF-State Output Current, VCC = 5.5V, −20 µA LOW Level Voltage Applied VO = 0.4V ICCH Supply DM74ALS257 VCC = 5.5V Outputs HIGH 3 6 mA Current DM74ALS258 Outputs OPEN 2.5 4 mA ICCL Supply DM74ALS257 Outputs LOW 8 12 mA Current DM74ALS258 7 11 mA ICCZ Supply DM74ALS257 Outputs Disabled 9 14 mA Current DM74ALS258 8 13 mA |
