ABSOLUTE MAXIMUM RATINGS Parameters Ratings Units Temperature Under Bias 55 to +125 C Storage Temperature 65 to +150 C Voltage on Any Pin with Respect to Ground (Note 2) 2.0 V to +V + 2.0 V V CC V with Respect to Ground 2.0 to +7.0 V CC Package Power Dissipation Capability (T = 25C) 1.0 W A Lead Soldering Temperature (10 secs) 300 C Output Short Circuit Current (Note 3) 100 mA Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 2. The minimum DC input voltage is 0.5 V. During transitions, inputs may undershoot to 2.0 V for periods of less than 20 ns. Maximum DC voltage on output pins is V + 0.5 V, which may overshoot to V + 2.0 V for periods of less than 20 ns. CC CC 3. Output shorted for no more than one second. No more than one output shorted at a time.
