Note: Stresses above those listed may cause permanent
damage to the device. This is a stress rating only and
functional operation of the device at these conditions, or at any
other condition above those indicated in the operations section
of this specification, is not implied. Exposure to absolute
maximum ratings for extended periods may affect device
reliability.
