Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. 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.
