Hi, as the title says, I'm looking for an IC that can switch the output from high to low and back based on just one input pulse signal, I have thought about using flip flops but those need clock and I intend to use it in a feedback circuit for a Tesla coil which will be hard to tune the clock signal(I'm basically looking for a T-flip flop that doesn't need clock). Are there any ICs like that, please let me know, thanks a lot!

 

You can use a flip flop that requires a clock by using the “input pulse signal” as the clock. A T flip flip (or another type like a D wired as a T) will work. A clock doesn’t have to be a timed signal; many applications are made possible by using the clock pin as an input.

 

How about a monostable 555 timer?

 

The FF "clock" can be the input pulse signal.
The FF clock input is just the input that causes the FF output to change state, depending on the value of the control input(s).
Why do you think it's different?

 

With the correct flipflop, such as a CD4013, a toggle circuit has only one input. The pulses from the switch go to the clock input, and the Q and Q- outputs change state with each press.

To be clear, the "clock" signal in both #5 and #6 can be a de-bounced switch signal. It does not have to be a system clock or some other kind of oscillator signal.

There are two schemes that can do what I think is requested, which is really just providing a pulse and it's compliment when a puls is delivered. That could be a CD4528, a CD4538, or even a CD4013 RS flipflop connected as a "flopshot" which is a FF that changes state back after some time interval. But the delay is more temperature dependent than the first two.

While you can use any signal for your clock signal to an FF, as suggested by many of the posts above -- you would need two pulses, one to set the output from HI to LO and another to set it back to HI. Based on what you've written, it sounds like you want the output signal to make two transitions (HI to LO followed by LO to HI) in response to a single input pulse. Is that correct? If so, you need some means of determining how much time elapses between the two transitions. For many applications, this is just was a 555 timer circuit is meant for. Look up "one shot", or "astable multivibrator", or just "555 timer".

If, instead, you mean that you want one physical signal, but want one pulse of that signal to set the output LO and the next pulse of that signal to set the output back HI, then that is something that a T-type FF (which can easily be implemented from any other kind of flip flop) would be good for. Though you probably also need to incorporate some kind of a reset signal so that you can force it into a known state.

 

The TS asked for a device that will deliver a single pulse for a single input pulse. I described the devices in post #8. Read post#1 carefully.
One single pulse to trigger a defined output pulse that rises and falls after some time delay. That exactly describes a non-retrigerable one-shot, like the ones I listed.

 

Combined with the thread title, the wording in post #1 is ambiguous.

Yes. The IC is called a one-shot “multivibrator” or “timer”.

 

Like I said in posts #8 and #10. all of those devices have both "true" and "complement" outputs.
