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
listed in the operational sections of this specication) is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
