(1)
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2)
If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office / Distributors for availability and
specifications.
(3)
The maximum power dissipation must be derated at elevated temparters and is dictated by TJ-MAX (maximum junction temperature),
RΘJA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PD-MAX = (TJ-MAX – TA)/RΘJA or the number given in the Absolute Maximum Rating, whichever is lower.
