E elec123 New Member Mar 26, 2004 #1 Hi, I need a switch debounce circuit for my project, (see attatchment) Could someone please explain how this circuit works, also is the picture suggesting the NAND gate needs a square wave input on one of its inputs? Any feedback welcome Thanks Attachments bounce1b.gif 7.2 KB · Views: 479

Sebi Active Member Mar 26, 2004 #2 The cross-coupled gates (RS flip-flop) work as debouncer. As You see, the output clear. The circuit just show: no problem with signal transfer (third gate). Attachments bounce1b_159.gif 7.6 KB · Views: 599

Other types of Bounce suppressor (using resistor / capacitor delays have been discussed in this forum. So search for "Bounce Suppressor" or search my posts as I made contributions. Len
