    I got a few of these, SNC54LS76AJ, and I don't remember what they are or where they come from. Searching for a datasheet, gives me a bunch of results in Chinese, or some other language I don't understand.

    Anyone?

    Another IC.
    So that means SW7448-N is equal to SN74LS48, which is a BCD to 7 segment decoder/driver?

    actually the 54 series is the same as the 74 series, only has tighter specifications. a 5476 is the same function as a 7476. usually higher temperature specs too.

    OK... So I don't remember what NOS stands for, so I checked Wikidedia.

    I'm going for Not Otherwise Specified.

    And that is quite correct.
