NOTE: (1) Stresses beyond those listed under the Absolute Maximum Ratings
may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond
those indicated under the Recommended Operating Conditions is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may
affect device reliability.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments 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 degrada-
tion 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.
