Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional. For verified specifications and test conditions, see the Electrical Characteristics.

(2)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

All limits are specified. All electrical characteristics having room temperature limits are tested during production with TA = TJ = 25°C. All

hot and cold limits are verified by correlating the electrical characteristics to process and temperature variations and applying statistical

process control.

(2)

Device thermal limitations may limit usable range.
