Other Parts Discussed in Thread: SN65HVS882

Hi everyone

i would like in the frame of a project to do spice SPICE simulations with the software Multisim (NI)

That's basically the circuit i want to simulate

1256.High Voltage DI design.pdf

For the ISO7242, I have thought about using 4 basic optocouplers (with photodiode & diode), then i saw in the document above, page 17, that ther was a device I/O schematics, so i'm wondering if i should follow it or no (the point is that i didn't really catch it)

Beside, i don't know at all how to do for the serializer SN65HVS882 in order to simulate it (no documents found in TI website)

I have already read the tutorials in National instruments website but i don't really know how to simulate this.

If someone have got some advice i would be very thankful

Thans for your attention

Unfortunately we don't use Multisim NI here. In fact many customers required small evaluation modules (EVMs) for both devices as they figured they need to build the circuit up anyway once the simulation is done. So we offer these EVMs on our website where you can order them.

Hi Thomas Kugelstadt

I just have a question about the LEDs you used in your design. I couldn't find simple LEDs to use, but i found these ones DS67. The problem is that we don't have enough space in our card to use these ones ( we would like 24 , one for each input) Do you have any idea about it?

Thanks in advance for your help

Regards, Badr

ahh we don't need high voltage LEDs !!!!
