†

Notice:

Stresses above 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 those or any other conditions above those indicated in

the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.
