*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 VDE 0884 Insulation Characteristics Table (if applicable), your

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