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