ELECTROSTATIC DISCHARGE SENSITIVITYThis integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled wi

th 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.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability.
