(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 measured with respect to GND = 0 V, unless otherwise noted.

(3)

If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
