I needed lm2901 for a project.
the thing I bought is a 14 pin SMD IC that has these things written on it:
2901
JRC
A26064L
Well, it obviousely seems to be a 2901 but it isn't!
simply it doesn't work! (don't say I should test some more chips, I've got 100
of them and have tested 3 of them. none of which works).
2901 contains four voltage comparators. But this IC seems to be something else. Should it be an IC, made for an OEM business (production under other companies names), so that 2901 is a special serial number in the company ordered them?
Have you got any ideas what the hell these 2901s can be?
