Debounced Multi-Switch Digital Module (using a hex inverter)

Debounced Multi-Switch Digital Module (using a hex inverter)
Hi guys! Thanks for watching. I needed some type of module with many debounced push button switches. So, this is my creation.
As I got building the project, I had the idea to add a hex inverter. Each push button sends a debounced high-to-low signal. But, because of the added hex inverter, each push button simultaneously controls a low-to-high output signal too.
Once again, each push button has two outputs (high-to-low and low-to-high). The signals can be tapped off the female-headers.
Overall, the project has four debounced push buttons. The result is eight different digital output signals. That should be plenty useful in experimenting with microcontrollers and other ICs.
I've been building things with popsicle sticks and glue for as long as I can remember. They're light-weight, strong, and lean. Quick and easy too!
Thanks. Have a great day!

Note to self: latching ICs are available.
