Minimum DC voltage on input or I/O pins –0.5 V During
voltage transitions, the input may overshoot V
SS
to –2.0 V
for periods of up to 20 ns. Maximum DC voltage on input
and I/O pins is V
CC
+ 5 V During voltage transitions, input
and I/O pins may overshoot to V

Stresses above those listed under “Absolute Maximum Rat-
ings” may cause permanent damage to the device. This is a
stress rating only; functional operation of the device at these
or any other conditions above those indicated in the opera-
tional sections of this specification is not implied. Exposure of
the device to absolute maximum ratings for extended periods
