*Notice: Stresses at or above those listed
under "Absolute 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 beyond those indicated
in the operational sections of this
specification are not implied.
Exposure to absolute maximum
rating conditions for extended
periods may affect device reliability
