4. Absolute Maximum Ratings
Stresses beyond those listed under âAbsolute Maximum Ratingsâ 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 operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
