Overview
Data register bank is an open-source printed circuit board by lafehubert, from the lafehubert/electronics repository on GitHub. It is a 4-layer board of 99.6 × 59.1 mm with 57 parts on 98 nets, routed with 717 tracks and 44 vias.
It is built around the 74LS173SC. Its parts include 26 diodes, 10 capacitors, 10 ICs, 2 resistors and 1 connector. It belongs with the FPGA and CPLD boards of this library.
Main components
1README
ya4b/slow-clock/README.mdThis slow clock was initially inspired by Ben Eater's design (https://eater.net/8bit/clock) but I found the 555 to be too fiddly for the monostable stage, and overkill for the bistable stage, so I used a 74LS123 for the former and an R-S latch made from a couple of NANDs on a 74LS00 for the latter. I also replaced the 74LS04 with a 74LS14 which seemed to clean up the waveform a good bit.

Questions
How big is the Data register bank PCB?
It measures 99.6 × 59.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Data register bank use?
57 parts, built around the 74LS173SC. 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 Data register bank KiCad files?
From the lafehubert/electronics repository on GitHub, at the commit this page was made from: the board is ya4b/data-register/data-register-bank/data-register-bank.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Data register bank design in my own project?
Its repository states no licence, so its author keeps all rights: ask lafehubert before reusing the design.
