This product described in this specification isn’t judged whether it applies to COCOM regulations. Please confirm in case of export.
This product isn’t designed for protection against radioactive rays.
Application example
The application circuit is recommended for use. Make sure to confirm the adequacy of the characteristics.
When using the circuit with changes to the external circuit constants, make sure to leave an adequate margin for external components including static
and transitional characteristics as well as dispersion of the IC.
Note that ROHM cannot provide adequate confirmation of patents.
The product described in this specification is designed to be used with ordinary electronic equipment or devices (such as audio-visual equipment,
office-automation equipment, communications devices, electrical appliances, and electronic toys).
Should you intend to use this product with equipment or devices which require an extremely high level of reliability and the malfunction of which
would directly endanger human life (such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel
controllers and other safety devices), please be sure to consult with our sales representative in advance.
