COMMENT
Stresses above those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only; the functional operation of
the device (at these or any other conditions above
those listed in the operational sections of this specifica-
tion) is not implied. Exposure to absolute maximum rat-
ing conditions for extended periods may affect device
reliability.
