Electrical Specifications
Absolute Maximum Ratings
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This
is a stress rating only, and the functional operation of the device at these or any other conditions above those listed
in the operational section of this specification is not implied. Exposure to absolute maximum ratings conditions for
extended periods may affect device reliability.
