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.
