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.
1. 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 CC +0.5 V, which may overshoot to V CC +2.0 V for periods of less than 20 ns.
2. Output shorted for no more than one second. No more than one output shorted at a time.
