NOTE: Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of
the device at these or any other conditions greater than those indicated in the operational sections of this specication is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
