Absolute Maximum Ratings
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales Office/
Distributors for availability and specifications.
Electrical Characteristics
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: For operation at elevated temperatures, the device must be derated based on a 150˚C maximum junction temperature and a thermal resistance of 80˚C/W
(DIP), 120˚C/W (SO-14) junction to ambient.
Note 3: Tested per Figure 1, V
Note 4: The Min/Typ Max limits are relative to the positive voltage peak seen at V
