Electrical Characteristics
Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent dam-
age to the device. Functional operation of the device at
these or any other conditions beyond those indicated in
the operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum rat-
ings for an extended period may degrade the device
and effect its reliability.
