(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 Section 6.3. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Absolute Maximum Ratings are limits beyond which damage to the device can occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For the Electrical Characteristics table for specifications and test conditions.
(3) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and specifications.
