7404N: common questions
Where can I find a 7404N reference design?
Each of the 3 boards on this page is a real design using the 7404N. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the 7404N?
The median is 177.8 × 152.4 mm, and 0% are two-layer designs.
What is the most popular open source board using the 7404N?
By GitHub stars, Cpu blitter inputs by clydeshaffer, with 146 stars.
Can I simulate one of these boards using the 7404N before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
