Latching ic, is there such a thing?

ok thanks for the help,now i dont need a bulky relay to do this simple job.

What are you going to do with the output of the toggle flip-flop?

Here is a simple toggle circuit. 3 of the circuits can be made with one IC. It has built-in debounce for the pushbutton.

Afternoon, I've come across this circuit during a google search and i would like to ask some questions if that would OK?? i can start a new thread if required depending on the answer i get as i don't wish to hijack this one (even if it is from 2007) basically i am looking to use this circuit to convert a door switch (Van side door) in to a momentary switch. would there be any issues with this circuit if it had the 12V supplied to it all the time the door was open? i know you talk about toggle switches further up but i was just hoping to clarify.

Thank You in advance

Not at all

I prefer the debounced toggle circuit below using the CD4013 D-FF.
It uses an RC to delay of the D feedback signal to prevent the FF from toggling more than once during the switch bounce time.
It uses only one R and one C, and doesn't degrade the clock signal rise-time.
For the values shown, the debounce lockout time is about 70ms.

AG's circuit in post #23 is also good.

Thank you for your reply.

so ultimately I'm not completely sure of how long/short the bounce will have to be.

Ill start a new thread not to muddy the water i think and explain my idea. I'm fairly basic at this but i know pretty much what i want, just not how to achieve it and id like to learn how. i'll drop a link here when its done
