NOTE: Stresses beyond those listed under Absolute

Maximum Ratings may cause permanent damage to the

device. These ratings are stress specifications only. Functional

operation of product at these conditions or any conditions be-

yond those listed in the DC Characteristics or AC Character-

istics is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect product reliability.
