Electrical Characteristics

Absolute Maximum Ratings are stress ratings. Stresses in

excess of these ratings can cause permanent damage to

the device. Functional operation of the device at these or

any other conditions beyond those indicated in the opera-

tional sections of this data sheet is not implied. Exposure

of the device to the absolute maximum ratings for an

extended period may degrade the device and effect its

reliability.
