† Notice: Stresses 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 those or any other conditions above those

indicated in the operational listings of this specification is not

implied. Exposure to maximum rating conditions for extended

periods may affect device reliability.
