structure, and other contents described herein at any time without notice in order to improve design or
reliability. Manufacturing locations are also subject to change without notice.
●Observe the following points when using any devices in this publication. SHARP takes no responsibility
for damage caused by improper use of the devices which does not meet the conditions and absolute
maximum ratings to be used specified in the relevant specification sheet nor meet the following
conditions:
(i) The devices in this publication are designed for use in general electronic equipment designs such as:
--- Personal computers
--- Office automation equipment
--- Telecommunication equipment [terminal]
--- Test and measurement equipment
--- Industrial control
--- Audio visual equipment
--- Consumer electronics
(ii)Measures such as fail-safe function and redundant design should be taken to ensure reliability and
safety when SHARP devices are used for or in connection with equipment that requires higher
reliability such as:
--- Transportation control and safety equipment (i.e., aircraft, trains, automobiles, etc.)
--- Traffic signals
--- Gas leakage sensor breakers
--- Alarm equipment
--- Various safety devices, etc.
(iii)SHARP devices shall not be used for or in connection with equipment that requires an extremely
high level of reliability and safety such as:
