(1) Stresses above these ratings may cause permanent damage. Exposure to

absolute maximum conditions for extended periods may degrade device

reliability. These are stress ratings only, and functional operation of the device

at these or any other conditions beyond those specified is not implied.

This integrated circuit can be damaged by ESD.

Texas Instruments 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 degradation

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.
