Stresses exceeding Absolute Maximum Conditions may
cause permanent damage to the device. These conditions are
stress ratings only. Functional operation of the device at these
or any other conditions beyond those indicated in the
operation sections of this data sheet is not implied. Extended
exposure to Absolute Maximum Conditions may affect
reliability.
