Absolute Maximum Ratings

Stresses above those listed under

Absolute Maximum Ratings may cause permanent damage to the device. These ratings are

stress specifications only and functional operation of the device at these or any other conditions above those listed in the

operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended

periods may affect product reliability.
