(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the

Operating Ratings. Specifications are not specified for parameters where no limit is given; however, the typical value is a good indication

of device performance.

(2)

All voltages are measured with respect to the ground pins, unless otherwise specified.

(3)

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

specifications.

Operation is specified up to 84V; however, distortion may be introduced from SPiKe protection circuitry if proper thermal considerations

are not taken into account. Refer to the THERMAL PROTECTION section for more information.
