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.

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.
