DC Electrical Characteristics
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: For 8 bits toggling, I
Note 4: Guaranteed, but not tested.
Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
