I want to assign corresponding footprint names for 74HC00.
But It is impossible for me to select appropriate footprint names from massive parts list…
Is there anyone know what footprint names I should select for 74HC00 NAND gate ?
Hi,
The footprint name describes the package of your 74HC00.
What type of package do you have, or what type do you intend using?
As jmk says, it depends on what package you intend to use. 74HC00 would come in at least DIP-14 or SOIC-14. You must have an idea of whether you are going to use TH or SM parts to build your board, otherwise you cannot continue.
The 74HC00 I am looking for is look like below link.

I think It is SOIC-14 type.But I don’t know whether it is TH or SM parts…
Frankly speaking I want to create below link of SMSReader with Strip Board.
And I have to change 50 pin connector(which name is SMSCART in the schematic) to 44pin connector,Because It don’t supports Japanese game cardridge. But it seems that The original creator of this schematic have removed most parts of footprint name,So I have to search for all of corresponding footname for all parts as well as 74HC00 in order to make correct PCB circuit which contains 44pin connector instead of 50 pin connector…

That’s a TH PDIP-14, 0.1" pin pitch. Electrically TH and SM will work the same, so you get to choose whether you want to solder TH or SM parts on your board.
By the way,Where is TH PDIP-14? I search for most of parts which belong to Package_DIP in the Assign Footprints window, But there is no part which contains “TH PDIP-14” in their name…
I’m not a gamer, but I couldn’t help noticing the project you linked to is very old and expects a parallel port on a PC. Wouldn’t it be better to look for a design that uses USB, for example this one?

Here you can see an example where the choices have been narrowed down for you:
The first choice is fine.

retiredfeline, Thank you very much for your link of SMS dumper! I dont even imagine that there really exist another PCB circuit of SMS dumper which make use of USB port!
But It is too bad that their homepage have been abandoned and I cannot find any feedback concerning this USB SMS dumper…
I have two old pentium 4 mainboard which supports parallel port, So for a first attempt, I will try to make SMSReader with Strip Board and If I succeed to make SMSReader,I will make your link of USB SMS dumper in the next place.
And I finally found that “DIP-14_W7.62mm” is the corresponding footprint name for 74HC00.I sincere thank you again for your invaluable information.I really appreciate your help!

Good luck and have fun. I suppose if you only want to dump some cartridges, you only need a single, viable setup for a short time, and don’t even need to get a PCB manufactured.

Thank you for your reply! obviously My first goal is to dump some japanese retro-game cartridges I currently have.But I also intend to imitate DIY circuit with Strip Board. Recently I really surprised at awesome DIY circuit which is designed by Western enthusiast…Frankly speaking,There is a bunch of retro-gamer in my country,But there is no one in my country who is willing to spread their schematic on the web…
It seems that I need to find out corresponding footprint names for L7805 voltage regulator in order to make correct PCB circuit…
The KiCAD LM7805 symbol already has the footpint (TO-220) attached to it…
The link below might help…

DIP-14 is what you find
