Hey all...
I wanted to swap a latching switch i am using in one of my circuits, for a nicer, cheaper momentary one.
Im having some problems figuring out what IC to use for the latching function.
There are no current requirements, it just has to output a signal. But it has to work off 12V.
There are alot of bi stable ICs out there at good prices, but they all seem to have a separate input for set and reset.
What I want is to use the one momentary input (from the switch) to toggle the output between high and low.
Would I be correct in assuming you cant just connect the set and reset inputs together, to get a single input bistable operation out of something like a d type flip flop?
Can anyone suggest an IC that I should look at for doing this?
Or should i be looking at more generic logic for acheiving this.
I dont really want to use a micro, just because of the lower supply voltage and complexity of programming it before soldering.
But if it gets to the point where the IC and associated debounce circuitry becomes as complex as programming an micro (which at least can perform simple dedicated timing operations like debounce) then I will do it that way.
