Hello,

74HC688.package pinout is wrong :
- it has two Q5 (the second should be P6)
- and P6 should be Q6

Good opportunity to make a new video tutorial :-D

Unfortunately, the new pinout shown in the video is wrong.


You changed it to "P4 Q4 P5 P6 Q5 Q6",
But it should be "P4 Q4 P5 Q5 P6 Q6".

I think my initial message was misleading. I'm sorry. I should have been clearer.

Here is datasheet : https://assets.nexperia.com/documents/data-sheet/74HC688.pdf

Thanks for the correction.

I did it how I understood to make a fast video, but didn't check if it was correct, so I didn't commit the change.

Now I can do the correct change and commit.
