How to Convert 5V to 24V output

There is a lot of way to convert pulse 5v to 24v, but of course people will try to find an easy way to do it and stable. On my Multi Fixed Pulse Generator the pulse output is 5V and with 5V power supply, but to match application to the field i have to convert it from 5v pulse to 24v pulse and the power supply 24V too. Because the power supply is 24V it's easy to convert it.

Here is the schematic :

As you can seen on this free circuit design, i use 7407 hex buffers. I choose this chip because it have high volt open collector output, that's why we have to use pull-up resistors on each output and connect it to 24V source. For detail about the calculation of the resistors value you can refer to the data sheet.

And here is the step down power supply 24v source to 5v output.
