Notes:
1. Derate linearly above +70°C free air temperature at a rate of 0.3 mA/°C.
2. Maximum pulse width = 10 µs, maximum duty cycle = 0.2%. This value is intended to allow for component tolerances for designs with IO peak
minimum = 2.0 A. See Application section for additional details on limiting IOL 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 µs, 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 > 4500 V
rms
for 1 second (leakage detec-
tion current limit I
I-O
< 5 µA).
9. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted together.
10. PWD is defined as |t
PHL
- t
PLH
| for any given device.
11. Pin 1 and 4 need to be connected to LED common.
12. Common mode transient immunity in the high state is the maximum tolerable dV
CM
/dt of the common mode pulse V
CM
to assure that the
output will remain in the high state (i.e. V
O
> 10.0 V).
13. Common mode transient immunity in a low state is the maximum tolerable dV
CM
/dt of the common mode pulse, V
CM
, to assure that the out-
put will remain in a low state (i.e. V
O
< 1.0 V).
14. 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.
15. The difference between t
PHL
and t
PLH
between any two HCPL-3180 parts under same test conditions.
