COMMENT
Stresses above those listed under âAbsolute Maximum
Ratingsâ 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 speciï¬cation) is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
