Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The analog inputs are protected as in the following circuit. Input-voltage magnitudes beyond the Absolute Maximum Ratings may damage this device.

(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.
(4) When the input voltage at any pin (other than VIN+ or VIN–) exceeds the power supply limits (that is, less than GND or greater than VA19), the current at that pin must be limited to 25 mA. The 100-mA maximum package input current rating limits the number of pins that can safely exceed the power supplies. This limit is not placed upon the power pins or thermal pad (GND).
(5) Reflow temperature profiles are different for lead-free and non-lead-free packages.
