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, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature),

RθJA (junction-to-ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any

temperature is Pdmax = (Tjmax – TA)/ RθJA or the number given in the Absolute Maximum Ratings, whichever is lower.
