*Notice: Stresses above those listed under âMaximum Ratingsâ
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at those or any
other conditions above those indicated in the operation listings of
this speciï¬cation is not implied. Exposure to maximum rating con-
ditions for extended periods may affect device reliability.
