Notes:
1. Minimum DC voltage on input or I/Os is –0.5 V During
voltage transitions, inputs or I/Os may undershoot V

to
–2.0 V for periods of up to 20 ns. See Figure 8. Maximum
DC voltage on input or I/Os is V

+ 0.5 V During voltage
transitions outputs may overshoot to V
CC
+ 2.0 V for
periods up to 20 ns. See Figure 9.
2. No more than one output may be shorted to ground at a
time. Duration of the short circuit should not be greater
than one second.
3. Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; functional operation of the de-
vice at these or any other conditions above those ndicated
in the operational sections of this data sheet is not implied.
Exposure of the device to absolute maximum rating condi-
tions for extended periods may affect device reliability.
