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.
