*Notice: Stresses above those listed under âMaximum Ratingsâ 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 speciï¬cation is
not implied. Exposure to maximum rating conditions for extended peri-
ods may affect device reliability.
