*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 specication is
not implied. Exposure to maximum rating conditions for extended peri-
ods may affect device reliability.
