| Dec 19, 2020 at 15:19 | comment | added | SteveSh | Decoupling capacitors on power supply rails are considered good design practice. But in this circuit - with it running off of a battery and using (by today's standards) slow parts (output rise and fall times around 50 ns with a 9V supply) - it probably is not really needed, as you noted. | |

| Dec 19, 2020 at 14:59 | comment | added | Unimportant | It's a decoupling capacitor for one or both of the IC's. I'd add a second one, so each IC has it's own. You're supposed to place them close to the IC they're decoupling and use as short traces as possible. | |
