NOTES: (1) Stresses beyond those listed under "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 "recommended operating conditions" is not implied. Exposure
to absolute-maximum-rated conditions of extended periods may affect device
reliability. (2) All voltage values are with respect to ground terminal.
ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling 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.
