Notes:
1. DC CURRENT TRANSFER RATIO (CTR) is dened as the ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100%.
2. Pin 7 Open.
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. Use of a resistor between pin 5 and 7 will decrease gain and delay time. Signicant reduction in overall gain can occur when using resistor val-
ues below 47 kΩ. For more information, please contact your local Avago Components representative.
5. Common mode transient immunity in a Logic High level is the maximum tolerable (positive) dV
CM
/dt of the common mode pulse, V
CM
, to assure
that the output will remain in a Logic High state (i.e., V
O
> 2.0 V). Common mode transient immunity in a Logic Low level is the maximum toler-
able (negative) dV
CM
/dt of the common mode pulse, V
CM
, to assure that the output will remain in a Logic Low state (i.e., V
O
< 0.8 V).
6. In applications where dV/dt may exceed 50,000 V/µs (such as static discharge) a series resistor, R
CC
, should be included to protect the
detector IC from destructively high surge currents. The recommended value is R
CC
= 220 Ω.
7. Use of a 0.1 µF bypass capacitor connected between pins 8 and 5 adjacent to the device is recommended.
8. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 4500 V rms for 1 second (leakage detec-
tion current limit, I
I-O
< 5 µA). This test is performed before the 100% production test shown in the IEC/EN/DIN EN 60747-5-2 Insulation Related
Characteristics Table, if applicable.
9. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 V rms for 1 second (leakage detec-
tion current limit, I
I-O
< 5 µA). This test is performed before the 100% production test for partial discharge (method b) shown in the IEC/EN/DIN
EN 60747-5-2 Insulation Related Characteristics Table, if applicable.

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