... Isn't the K1551D1 actually functionally equivalent to the 74141 rather than the 7441 (with a higher voltage rating also) ? The key difference between the...
... Didn't someone say the pinout was metric rather than 0.1" imperial on the Russian jobbies? So if your layout is extremely tight would it still be...

[edited by A.J. - please trim quoted material] ... The K155ID1 has identical logic to the 74141, which has different logic from the 7441. [Non-text portions of...
... John, Yes, vintage Russian DIP ICs are based on a pin grid of 2.50 mm rather than 0.1 inch (2.54 mm). The difference in length over a 16-pin DIP is 0.28 mm...

That's not cheating. Common practice. I always use shift registers as output expanders. In this case your chip select is going to be high active. If you have...
