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 indi-
cated in the operational sections of this specification) is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
