I was hoping that someone on these forums could double check my schematic to ensure this will work properly on my PCB.
I'm trying to debounce/deglitch three buttons using a schmitt trigger and rc circuit. I'm using a 74HC14. My question is, can I use R5(10k resistor) for all three buttons as a pull up resistor or does each button need to have its own? The image is rather small but that resistor is running to the 5v supply. I normally had the buttons attached to the trinket and used its built in pullup resistors but since I have to run through the 74HC14 on this design I can't use that feature. I just want to be sure that using this design will give me the desired result before I order the pcb's and wait several weeks for them to get here only to find I've made a mistake somewhere.
My other question is whether this rc circuit will have enough filtering to debounce the button or should I change the resistor or cap values to adjust the time? Thanks for your time!
