Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other condition beyond those included under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods of time may affect device reliability.
