    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

    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.
    Please don´t contact me via PM, because there is no time to respond to them. No friend requests. Thank you.

    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.
