9. The difference between t

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 VCMto assure that the output
will remain in the high state (i.e. VO > 15 V).
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 < 1.0 V).

13.In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 Vrms, 60 Hz for 1 second (leakage
detection current limit II−O < 10 mA).
14.Device considered a two−terminal device: pins on input side shorted together and pins on output side shorted together.
