*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
