Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are

stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the opera-

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

affect device reliability.
