Could I select a D Flip-Flop (DFF) part with RESET input pin ?

As title, may I get a DFF with RESET input from standard library ? Or I should start from combination logic ?

Thanks for your response.

Not sure of what is wanted, but a possible "auto setting at boot up" is to use pull down resistors to get a default value of 0, logic low.

Note that to avoid both set and reset value being high, which is not a valid combo for simple Flip Flop, a special arrangement should be used.

I may have a word about the pull-down resistor: with a low value, they will engage a high current when the switch is closed. Preferably, use high value resistance, in general.

Thanks for your idea.

I build it by combination logic from the web reference circuit, sharing to you, thanks again ^^
