* 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 60747-5-5 Insulation Characteristics Table (if applicable).
Notes:
1. Derate total package power dissipation, P
T
, linearly above 70°C free-air temperature at a rate of 4.5 mW/°C.
2. Detector requires a VCC of 4.5V or higher for stable operation as output might be unstable if VCC is lower than 4.5V. Be sure to check the power
ON/OFF operation other than the supply current.
3. Duration of output short circuit time should not exceed 10 ms.
4. Input capacitance is measured between pin 1 and pin 3.
5. Device considered a two-terminal device: pins 1, 2 and 3 shorted together and pins 4, 5 and 6 shorted together.
6. The t
PLH
propagation delay is measured from the 50% point on the leading edge of the input pulse to the 1.3 V point on the trailing edge of the
output pulse. The t
PHL
propagation delay is measured from the 50% point on the trailing edge of the input pulse to the 1.3 V point on the leading
edge of the output pulse.
7. CM
H
is the maximum slew rate of the common mode voltage that can be sustained with the output voltage in the logic high state, V
O
> 2.0 V. CM
L
is the maximum slew rate of the common mode voltage that can be sustained with the output voltage in the logic low state, V
O
< 0.8 V.
8. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥ 4500 V
RMS
(6000 V
RMS
for ACPL-W481) for
one second (leakage detection 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 60747-5-5 Insulation Characteristics Table, if applicable.
9. Pulse Width Distortion (PWD) is dened as |t
PHL
- t
PLH
| for any given device.
10. Use of a 0.1 µF bypass capacitor connected between pins 4 and 6 is recommended.
11. The dierence between t
PLH
and t
PHL
between any two devices under the same test condition.
