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 specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
