Longshot but maybe plugged in backwards?

He says that he’s sold many of these ICs. He has some buyers who constantly take these ICs. Never was problems.

I tried like 6 of them. Unless I’ve got a bad batch these KP525NCIA’s are NOT exact replacements for the MC1495’s.

I did, it worked, but wierdly . The text was reversed, it acted like a mirror. If your pot adjustment was slightly off to the right, it’d be slightly off to the left. These soviet chips are junk. They would work, but the image wouldn’t quite be right. I also found they hadn’t any notch on them as well as any signifier where pin 1 was located. I’d send them back but they came from Ukraine. I should have known better.

Found this on Soviet chips from chipdir:

525ПС1

MC1495, MC1595, AD532

Four Quadrant Multiplier

I’d try one on a board and give it the smoke test. J

Was looking for some 1495’s to keep in stock and came across an Ebay auction for some Russian equivalents. But it never stated what they were.

Well I received them the other day and have been trying to find any datasheets to find if in fact these ARE equivalent to the MC1495.

They are marked KP525NCIA and I can’t for the life of me find any info on them. Anyone else may have some info on these?
