Conditions
Note 1:
Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Functional operation under these conditions
is not implied.
Note 2:
Either voltage limit or current limit is sufficient to protect inputs.
Note 3:
Guaranteed but not tested.
