Note 2: “Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Range”
they are not meant to imply that the device should be operated at these lim-
its. The table of “Electrical Characteristics” provides conditions for actual
device operation.
Note 3: All voltages reference to ground.
