Storage temperature ......................... -65°C to +125°C

NOTES:
1. Operating temperature is for commercial product defined by this specification.
2. Minimum DC voltage is -0.5 V on input/output pins. During transitions, this level may undershoot to -2.0 V for periods < 20 ns.Maximum DC voltage on input/output pins is V_CC + 0.5 V which, during transitions, may overshoot to V_CC + 2.0 V for periods < 20 ns.
3. Output shorted for no more than one second. No more than one output shorted at a time.
