†
Stresses beyond 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 beyond those indicated in the "Recommended Operating Conditions" section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
