Hardware debouncing with 74HC14?
-
I spend some time on hardware debouncing circuits. As far as I've read doing this with a schmitt trigger is supposed to be the best solution. For this I found this nice IC 74HC14. Which houses 6 schmitt triggers. Maybe there are better solutions, if so just let me no. I also would like to use a combined schmitt trigger opto coupler IC but wasn't able to find one with more than one channel.
But it's more than enough for the project I want to use it for. I just want to be able to connect 5 binary inputs. I just want to get rid of the soft debounce. It uses memory and execution time. And for it's costs it's a great addition to my node here are 10 pieces at aliexpress
Since I'm new to schmitt triggers I googled for an example. Would this do the trick? One capacitor and 6 resistors?!
Example circuitThanx in advance
