(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) All voltages are with respect to the potential at the GND pin.
(3) If Military/Aerospace specified devices are required, contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(4) The part cannot dissipate more than 400 mW.

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) Absolute Maximum Ratings are limits beyond which damage to the device might occur. Recommended Operating Conditions are
conditions under which operation of the device is ensured. Recommended Operating Conditions do not imply ensured performance
limits. For verified performance limits and associated test conditions, see Electrical Characteristics.
(2) All voltages are with respect to the potential at the GND pin.
