Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply

when operating the device outside of the limits set forth under the operating ratings which specify the intended range of operating

conditions.

(2)

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

specifications.

(3)

The maximum power dissipation which can be safely dissipated for any application is a function of the maximum junction temperature,

circuitry will protect the device by reducing the output voltage as required to maintain a safe junction temperature.
