NOTE:
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 in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. SGMICRO 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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary
without notice at any time. Please contact SGMICRO sales
office to get the latest datasheet.
