“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be ensured. 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.
(2)
If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3)
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.
