Notes:
1. Derate linearly above +79°C free air temperature at a rate of 0.37mA/°C.
2. Maximum pulse width = 10µs, maximum duty cycle = 11%.
3 Derate linearly above +79°C, free air temperature at the rate of 5.73mW/°C.
4. No derating required across operating temperature range.
5. In this test, VOH is measured with a dc load current of 100mA. When driving capacitive load VOH will approach VDD
as IOH approaches zero amps.
6. Maximum pulse width = 1ms, maximum duty cycle = 20%.
7. tPHL 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 VO signal. tPLH 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 VO signal.
8. PWD is defined as | tPHL – tPLH | for any given device.
8. The difference between tPHL and tPLH between any two FOD3182 parts under same operating conditions, with
equal loads.
10. Pin 1 and 4 need to be connected to LED common.
11. Common mode transient immunity in the high state is the maximum tolerable dVCM/dt of the common mode pulse
VCM to assure that the output will remain in the high state (i.e. VO > 15V).
12. Common mode transient immunity in a low state is the maximum tolerable dVCM/dt of the common mode pulse,
VCM, to assure that the output will remain in a low state (i.e. VO < 1.0V).
13. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000Vrms,
60Hz for 1 second (leakage detection current limit II-O < 10µA).
14. Device considered a two-terminal device: pins on input side shorted together and pins on output side shorted
together.
