RECOMMENDED OPERATING CONDITIONS
Stresses above those listed under âAbsolute Maximum
Ratingsâ may cause permanent damage to the device.
This is a stress rating only and the 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.
