Stresses listed under Absolute Maximum Ratings may cause
permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other
conditions outside those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum
rating for extended periods may affect device performance and
reliability.
