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.

NOTES: (1) 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) Short-circuit to ground.
