Notes:
1. DC CURRENT TRANSFER RATI0 (CTR) is
defined as the ratio of output collector
current, IO, to the forward LED input current,
IF, 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. Significant
reduction in overall gain can occur when
using resistor values below 47 kΩ. For more
information, please contact your local HP
Components representative.
5. Common mode transient immunity in a Logic
High level is the maximum tolerable
(positive) dVCM/dt of the common mode
pulse, VCM, to assure that the output will
remain in a Logic High state (i.e., VO > 2.0 V).
Common mode transient immunity in a Logic
Low level is the maximum tolerable
(negative) dVCM/dt of the common mode
pulse, VCM, to assure that the output will
remain in a Logic Low state (i.e., VO<0.8 V).
6. In applications where dV/dt may exceed
50,000 V/µs (such as static discharge) a
series resistor, RCC, should be included to
protect the detector IC from destructively
high surge currents. The recommended value
is RCC = 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 detection current limit,
II-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 detection current limit,
II-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. For the continuous voltage rating refer to the IEC/EN/DIN EN60747-5-2 Insulation Characteristics Table (if applicable), your equipment level
