Note:
(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute
Maximum Ratings do not imply functional operation of the device at these or any other conditions
beyond those listed under Recommended Operating Conditions. If used outside the Recommended
Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully functional,
and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) All voltages are with respect to network GND.
