DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas Instru-

ments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling

and installation procedures can cause damage.

ESD damage can range from subtle performance degrada-

tion to complete device failure. Precision integrated circuits

may be more susceptible to damage because very small

parametric changes could cause the device not to meet its

published specifications.

NOTE: (1) Stresses beyond those listed under the Absolute Maximum Ratings

may cause permanent damage to the device. These are stress ratings only,

and functional operation of the device at these or any other conditions beyond

those indicated under the Recommended Operating Conditions is not implied.

Exposure to absolute-maximum-rated conditions for extended periods may

affect device reliability.
