6 Electrical Characteristics
6.1 Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings“ may cause permanent damage to the device.
These are stress ratings only. Functional operation of the device at these or any other conditions beyond those
indicated under “Operating Conditions” is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
