*Notice: Stresses beyond 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 is not implied. Exposure to absolute

maximum rating conditions for extended periods may

affect device reliability.
