* Notice: Stresses above those listed under “Maximum
Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of
the device at these or any other conditions above those
indicated in the operational sections of the specifica-
tions is not implied. Exposure to maximum rating con-
ditions for extended periods may affect device
reliability.
