*Stresses greater than those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
these or any other conditions above those indicated in the
operation section of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
** All voltage values are with respect to GND.
