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 Free Air Temperature Range Note 2: For I/O ports, IIH and IILparameters include the 3-STATE output current (IOZL and IOZH). Switching Characteristics Over Recommended Operating Free Air Temperature Range Supply Voltage 7V Input Voltage Control Inputs 7V I/O ports 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 53.0 °C/W M Package 72.0 °C/W Symbol Parameter Min Typ 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 −15 mA IOL LOW Level Output Current 24 mA TA Operating Free Air Temperature Range 0 70 °C Symbol Parameter Test Conditions Min Typ Max Units VIC Input Clamp Voltage VCC = Min, II = −18 mA −1.5 V VOH HIGH Level VCC = 4.5 to 5.5V IOH = −0.4 mA VCC − 2 Output Voltage VCC = Min IOH = − 3 mA 2.4 2.9 V IOH = Max 2 VOL LOW Level VCC = Min IOL = 12 mA 0.25 0.4 V Output Voltage IOL = 24 mA 0.35 0.5 II Input Current at Maximum VCC = Max.
