Absolute Maximum Ratings
are stress ratings. Stresses
in excess of these ratings
can
cause
permanent
damage 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 ratings for an
extended
period
may
degrade the device and
affect its reliability.
