Notes

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

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

Note

• As per IEC 60747-5-5, § 7.4.3.8.2, 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
