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

Legal issue with Fairchild, due to the
Fairchild/National split, is forcing the change from
CN74F which is 'Fairchilds' product code to CN54F
which is 'Nationals' product code.
