I'm trying to learn how to use a CD4013 with a momentary switch to create an on/off latch signal that can then be fed into a DG413 as a 3PDT audio switch (audio in, audio out, led on/off).

• +/-15v from a TEC 2 0923
• SOIC form

As I understand it, the DG413 is a quad that can act like a DPDT (audio in, out). The LED would simply be turned on/off using the CD4013. So I think I get how to wire the DG413, but I'm not getting the CD4013. I have the datasheet but I'm struggling to find an appropriate circuit example.

Thanks for any help you can provide!

 

Here's a discussion of that. @crutschow proposes 2 schemes, one of them worked for me. Both should work but I was dealing with dodgy components back then.

If I had to do it again I'd use an inverter.

For your purposes you might consider a CD4053.

edit:
For higher performance you might consider a CD74HC4053. Here's an example that I put in a chorus pedal:

 

The cd5053 only has 3, instead of 4 on the 4013 so that won’t work.

The chorus pedal schematic won’t load, gives an error. Can you check that?

1st thread has a lot of good info, thanks!

 

The chorus pedal thing lacks a debounce. The footswitch that I use is latching. It's essentially the same as in the geofex link.

If you need debounce and have a CD4013 to spare you can use that for debouncing:
