Limiting values
[1]
Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under Section 9. is not implied. Exposure to absolute-maximum-rated
conditions for extended periods may affect device reliability.
[2]
The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
