Absolute Maximum Ratings(Note 2)
Recommended Operating
Conditions
Note 2: 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 3: Either voltage limit or current limit is sufficient to protect inputs
DC Electrical Characteristics
Note 4: For 8-bit toggling, ICCD 0.8 mA/MHz.
Note 5: Guaranteed, but not tested.
