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.

These devices meet the following planned eco-friendly classification:
Green (RoHS and No Sb/Br): Texas Instruments defines Green to mean Pb-free (RoHS compatible) and free of bromine (Br)- and
antimony (Sb)-based flame retardants. Refer to the Quality and Lead-Free (Pb-Free) Data web site for more information. These devices
have a Cu NiPdAu lead/ball finish.
