Absolute Maximum Ratings
If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
Recommended Operating Conditions
Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage
to the device may occur. Operating Ratings indicate conditions for which the
device is intended to be functional, but do not guarantee specific perfor-
mance limits. For guaranteed specifications and test conditions, see the
Electrical Characteristics. The guaranteed specifications apply only for the
test conditions listed.
