† 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 operation listings of this specification is

not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability
