†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 listings of this specification is not implied. Exposure to maximum

rating conditions for extended periods may affect device reliability.

‡Notice: The device is not guaranteed to function outside its operating ratings.
