4 Electrical Characteristics
4.1 Absolute Maximum Ratings
Stresses above those listed in 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 conditions beyond those indicated
under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability.
