Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.

All voltages are with respect to ground, unless otherwise specified.

The input and output voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
