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 ;-)

A vague statement .... imposible to give help.I see there are many option of 74F151A, but not sure which one is the correct for me.
(Sorry for the wrong order of posts now)

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

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.
