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.
