    What a great video, wow. I'm watching this at 4 am and I'm not even studying EE. I'm truly amazed that this explanation is so easy to understand.

    Great video! I’ve spent the last two days trying to understand this component, and you have explained it perfectly 👌

    Good morning "toaster guy". I am happy to see you have a video on this subject. I really enjoy your videos! With toast and coffee of course.

    Usually SR/RS latches have a priority by design. So SR would be set priority, RS would be reset priority. I don't know if any priority is codified for the 555 or if all manufacturers cook their own stew here. But it should be consistent at least within batches.
    Maybe i dig around in my chip collection and whip up a bistable circuit. IIRC i should have at least chips by 3 different manufacturers.
    I think it with worth exploring since the 555 is an easy to use flipflop for example in power on reset circuits, or as part of an interlock.

      This will be a great thing to comment on and discuss once the bistable video is up as well, as I did a terrible (non-existent) job of explaining where you'd want to use a bistable 555 configuration. 😬

    Why do you need flip flop and inverter why not just take opamp output

    Calling it a timer was a bit of a misnomer, but I can see why they chose it. Too many other things this circuit could have been named depending on how it was put together.

      I think hearing it called a 555 timer and then learning about the bistable configuration really confused me as an undergrad. Frankly, it still confuses me but I guess I'm just used to it now.

      @@CircuitBread Wow, I got a reply! You guys are great. Thank you.
      The best way I had to learn of its implementation was, through a design inspired by Ben Eater. The guy who built a working CPU and memory using 7400 series ICs, on a ton of breadboards.
      I basically made a variable time clock output using all three states of the 555, so I used a 556 and one 555.
      A resistor and capacitor are used to provide a range of frequencies when a potentiometer or variable capacitor is introduced giving that nice astable clock.
      Then another 555 is put together with a push button to see that the bistable state is just the latch being a latch.
      Finally, the last 555 is just there for a variable interrupt, when also set up with a pot and push button for the monostable mode.
      This is a great project and really helped me see why set up a circuit this way in the first place.
      It was great to learn, but someone really needs to have understood the operation of two transistors in a feedback loop, or how the wizards want to call it a "Bi-stable multivibrator".

      Awesome! Ben Eater is incredible, I have tons of respect for that guy. And a hefty dose of jealousy for his brains. He reminds me a lot of my older brother. I'm glad that he was able to help your understanding as well!
      And I've gotten much worse at replying to comments (too dang busy) but I try when I can!

    So well explained that even me a third world Neadertal can understand.
