I was looking for optocouplers from the search menu using Fritzing and it didn’t show anything. Yet, I was able to find an obsolete part 4N35 6-pin IC. I could use a 4N25 of if anyone can build an LVT847.
A google search of the form “fritzing part LVT847” (which is the best way to find available fritzing parts) turns up several hits with parts. Don’t know it the parts are good quality or not though, try them and see.
