Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: Absolute maximum ratings are those values beyond
which the safety of the device cannot be guaranteed. Con-
tinuous operation at these limits is not intended; operation
should be limited to those conditions specified under DC
Electrical Characteristics.
