Absolute Maximum Ratings(Note 1)
Recommended Operating
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.
DC Electrical Characteristics
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
Note 3: For 8 bits toggling, ICCD  0.8 mA/MHz.
Note 4: Guaranteed, but not tested.
