Absolute Maximum Ratings
(Note 4)
Recommended Operating
Conditions
Note 4:
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 5:
Either voltage limit or current limit is sufficient to protect inputs.
DC Electrical Characteristics
