* The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous

voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 60747-5-2 Insulation Characteristics Table (if applicable), your

equipment level safety specification, or Avago Technologies Application Note 1074, “Optocoupler Input-Output Endurance Voltage.”
