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 data sheet is not implied. Exposure of
the device to absolute maximum rating conditions for extend-
ed periods may affect device reliability.
