Notes:
1. Derate linearly above +70 °C free air temperature at a rate of 0.3 mA/°C.
2. Maximum pulse width = 10 us, maximum duty cycle = 0.2%. This value is intended to allow for component tolerances for designs with I
O
peak
minimum = 2.0 A. See Application section for additional details on limiting I
OL
peak.
3. Derate linearly above +70 °C, free air temperature at the rate of 4.8 mW/°C.
4. Derate linearly above +70 °C, free air temperature at the rate of 5.4 mW/°C. The maximum LED junction temperature should not exceed +125 °C.
5. Maximum pulse width = 50 us, maximum duty cycle = 0.5%.
6. In this test, V
OH
is measured with a dc load current. When driving capacitive load V
OH
will approach V
CC
as I
OH
approaches zero amps.
7. Maximum pulse width = 1 ms, maximum duty cycle = 20%.
8. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 3000 V
rms
for 1 second (leakage detection
current limit I
I-O
< 5 uA).
9. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted together.
10. t
PHL
propagation delay is measured from the 50% level on the falling edge of the input pulse to the 50% level of the falling edge of the V
O
signal. t
PLH
propagation delay is measured from the 50% level on the rising edge of the input pulse to the 50% level of the rising edge of the V
O
signal
11. t
PSK
is equal to the magnitude of the worst case difference in t
PHL
and/or t
PLH
that will be seen between units at any given temperature within the
recommended operating conditions
12. PWD is defined as |t
PHL
- t
PLH
| for any given device.
13. Pin 1 and 4 need to be connected to LED common.
