– OCTOBER 2006 – REVISED AUGUST 2011

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.

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.

(2)

Long-term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction of

overall device life. See http://www.ti.com/ep_quality for additional information on enhanced plastic packaging.
