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 ;-)

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