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)
Refer to RETS135H for military specifications.
(3)
If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4)
Soldering process must comply with the Reflow Temperature Profile specifications. Refer to http://www.ti.com/packaging.
