| Post more images of the board and other components, especially any connectors! This sometimes helps identify the board. |

Meaning me?
Nope, I didn't think so. As far as I know Mixeur speaks russian, so he just transcripted russian letters into english. It's just that it doesn't help a tiny bit

Hi Marcin,
I have found a similar looking chip on eBay. It is a military grade IC. (This particular one is a 2x NAND gate).
I think that your K1LB341 is a soviet clone of them.
Could you take the photo of the whole board? |

???????????????
How do you come to this conclusion? I have some of these Russian IC in stock, just with other printing. But I wont say these are clones of a SMD 7401...

I did't say that the K1LB341 is a SN7401 clone. I want to say that the soviet K1LBxxx IC family could be clone of the milspec SN74xx family.
And if the K1LB341 is a simple logical gate, it is possible to check it with the logic analyzer to figure out what kind of gate it is! Most soviet clones have identical pinouts with their western originals. |
