(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 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) Stresses applied above VIN(DC) and below VIN(SHORT) should be limited to less than 100 hours over the lifetime of the device.  These stresses may occur during brief transient events but DC voltages in this range should not be applied.
