Hi

I need an electronic component which switches a 24V output signal on/off when it receives a 24V incoming pulse. I already figured out that this basically is an XOR transistor with outgoing signal re-entering it and found a suitable component here.
Now I'm stuck with how I can realize this component such that I can connect wires to it coming from other devices.
- Do I need to make a circuit board (and how can I do this?)
- How do I convert the incoming 24V to 5V and outgoing 5V to 24V? (I didn't find such a thing directly working on 24V...)
- How do I power the component?

Also, I see that there are 5 pins on the XOR component -> I only expected three :-S

Many thanks for helping me out!

There are 3 pins for logic as you expected, but you probably forgot about powering the component, that's what other two pins are for.

You may want to reconsider using a communication switch for your application. Check https://datasheets.maxim-ic.com/en/ds/MAX4659-MAX4660.pdf. The IC offers a wide output range supply with a very good input signal consideration. Hope this help. Is this for communication? Have you consider using a direct relay application?:p

If this does not serve your purpose, consider the reducing of the incoming pulse to TTL level using simple divider network. This can feed a monostable which in turn drive a higher voltage driver like Darlington pair.

If I may ask - why would you want to take 24V signal down to 5V when you will ultimately need a digital output back at same 24V level? It will help in answering question better if the above did not solve it.
