† 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 list-

ings of this specification is not implied. Exposure to maximum

rating conditions for extended periods may affect device reli-

ability.
