Note 1.All voltages with respect to GND. Currents are positive into, negative out of the specified terminal. Consult

Packaging Section of Databook for thermal limitations and considerations of packages.

2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.
