I recently needed to level shift from 5v to 3.3v. There are about a million different ways to do so, and most of which are using ICs that of course are not in my parts box (not because they shouldn’t be :P). What do you do when you have a new toy and no way to use it? The same thing you do when all you have is a hammer. You hammer stuff. I have plenty of discreet components so I started finding ways to make it work.
I know other people are going to have the same problem even though this is a pretty common problem with many possible solutions. I’m going to compile a list of ways to do it with varying parts so when you only have a hammer you can find something to nail. I’m not going to limit it to discreets though. You’ll find the 74’245 in here soon enough.
