Hi there

Looking for IC F151A 3204CRT or alternative as I can't find any details in the internet.

This IC used in old desktop motherboard.

Attached photo.

Hi,

I vote for standard logic IC: SN74F151A

Of you don't think so:
* show a better detailed photo (at your photo the outines are not clear...and one side seems to have 7 pins, the other 8 pins)
* give more details of the connections and the connected devices around (fast cache SRAM?) or show a bigger photo.

Is seems the contacts are corroded. Did you operate it with saltwater sprayed on it?
I recommend to treat it (and other electronics) more carefully ;-)

Klaus

Thank you Klaus for replying.

I will go today to electronics market and check for this option.

I see there are many option of 74F151A, but not sure which one is the correct for me.

A vague statement .... imposible to give help.

I recommend to read through the datasheet, then ask a more detailed question.

Klaus

Btw: the suffix "A" may be the version of silicon.
So don't be surprised if only "B" is available now. It should be 100% compatible.

from other side (down side), the IC has number - 56A24
 

A 74F151 is a 74F151.
It describes a logic function, they may be available from different manufacturers but they should all function identically.

Clean up that board first though - including what looks like a corroded via hole.

Brian.
 

Hi,

I ordered F151A from china, yesterday received.

Replaced and working fine.

Thank you for support.
