Note

• Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering

evaluation. Typical values are for information only and are not part of the testing requirements.

Note

• As per IEC60747-5-2, § 7.4.3.8.1, this optocoupler is suitable for “safe electrical insulation” only within the safety ratings. Compliance with

the safety ratings shall be ensured by means of protective circuits.
