† 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 rat-

ing conditions for extended periods may affect device

reliability.
