Hello, apparently I have stumbled upon an error on Multisim 11 optocouplers.
HCNR201, a dual photodiode-single LED precision optocoupler is shown as it
were made by a LED lighting two phototransistors, together with its SPICE model.
The worst thing, in my opinion, is that original photodiode cathode and anode are
now connected to collector and emitter of their transistor counterparts, resulting
in opposite polarization of the real devices if mounted on a pcb, not to mention the
bunch of doubts related to the effectiveness of a simulation of a circuit empoying
such device.
