NOTE: (1) Stresses above those listed under

Absolute Maximum Ratings may

cause permanent damage to the device. Exposure to absolute maximum

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 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.
