(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those listed in the Recommended
Operating Conditions table. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Applies to static and dynamic signals including overshoot.

(1) It is recommended to connect the V33A pin and the V33D pin to the same supply. V33A must be powered before V33D if sourced from
different supplies. There is no restriction on the ordering sequence for powering off.
