Notes:

1. Bypassing the power supply line is required with a 0.1 µF ceramic

disc capacitor adjacent to each optocoupler as illustrated in Figure

19. The power supply bus for the optocoupler(s) should be separate

from the bus for any active loads, otherwise a larger value of bypass

capacitor (up to 0.5 µF) may be needed to suppress regenerative

feedback via the power supply.

2. Peaking circuits may produce transient input currents up to 100

mA, 500 ns maximum pulse width, provided average current does

not exceed 5 mA.

3. Device considered a two terminal device: pins 1, 2, 3, and 4 shorted

together, and pins 5, 6, 7, and 8 shorted together.

4. The t

trailing edge of the input pulse to the 1.5 V point on the trailing

edge of the output pulse.

5. The t

leading edge of the input pulse to the 1.5 V point on the leading

edge of the output pulse.

6. CM

8. C

9. In accordance with UL 1577, each optocoupler is momentary with-

stand proof tested by applying an insulation test voltage ≥4500

Vrms for 1 second (leakage detection current limit, I

test is performed before the 100% production test for partial dis-

charge (Method b) shown in the IEC/EN/DIN EN 60747-5-5 Insula-

tion Characteristics Table, if applicable.

*The Input-Output MomentaryWithstandVoltage 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 60747-5-5 Insulation Characteristics Table (if applicable), your equipment level

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