(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 indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Condition not to exceed 100 hours at 25°C lifetime.
7.2 ESD Ratings
VESD Electrostatic discharge
Human-body model (HBM) (1)
All pins except E2
Pin E2
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
