Its kind of interesting: the 555 is such _horrible_ timer. It can't do a 50% duty cycle without extra BOM parts, even more parts to make a real PWM out of it, and it has terrible temperature and voltage stability. But somehow it persists.
“Hi, Jeff H., I have almost never used a 555. Maybe never? I use op-amps, LM324's, LM311's, LF356's. I use 74HC04's and 74C14's but not 555's. I've used ECL fast logic, and discrete transistors. But the 555 just does not do anything precise, or even semi-precise, that I need done. So that's one thing I can "share" - my favorite circuit to use a 555, is: a blank piece of paper. Never touch the things. Go ahead and print that. / rap”
