NE558 drop-in replacement

This is a drop-in replacement for the Texas Instruments NE558 quad timer IC based on two Texas Instruments NE556 dual timer ICs. It is primarily intended for joystick interfaces and similar applications. Other applications might need adjustments to the support circuitry.

The design has not been verified, yet.

Questions

How big is the Ne558 replacement PCB?

It measures 10.9 × 21.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Ne558 replacement use?

4 parts, built around the NE556. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Ne558 replacement KiCad files?

From the roybaer/ne558_replacement repository on GitHub, at the commit this page was made from: the board is ne558_replacement/ne558_replacement.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ne558 replacement design in my own project?

Its repository states no licence, so its author keeps all rights: ask roybaer before reusing the design.
