Operation outside the Absolute Maximum Ratings may cause permanent damage to the device. Absolute Maximum Ratings do
not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operation
Condition. 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.
8.2 ESD Ratings

(1)
JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2)
JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
