Note:
Stresses greater than 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 this
specification is not implied. Exposure to
absolute maximum rating conditions for
extended periods may affect reliability.
