·Hi, I want to interface this circuit from the 7404 to a ps2502-4 opto-isolator then to the BS2p40.
·Question is this circuit from the open-collector outputs going to the 74ls00 o.k.

· p.s. when you open the file could you please·use the + magnifier, for some reason the image is garbled with out it. I,m new at the sch program so please forgive me·for the inconvince.

    Typically, in a public forum such as this, you will want to print the file to a more common format, such as pdf, so that everyone can view it.

    You need a print driver that can print to a PDF file. I use PrimoPDF.

    allie: A quick & dirty way to make a jpeg or bmp file of anything on your screen is to hit PRINT SCREEN, then paste that into any image program, even MS paint.
