    Long time ago I learned a bit how to use LS type of IC ...

    Now there's a lot of news families (HC, LS , Plain TTL ...)
    Can someone gives me some ideas about what are diffrences between them ?

    Plain TTL, LS, is the old stuff. They use lots of power and the logic highs
    and lows sit somewhere inside the 5V supply.
    74HCxxxx offers the same functions (and more) but is nearly "perfect!".

    No, I'm not impersonating a turkey, I'm trying to express my utter
    frustration in peoples distinct lack of ability when it comes to
    finding information on the net.

    try these search terms;
    logic family comparison, CMOS, Low Power Schottky, TTL etc etc.

    You'll get HEAPS of stuff, a few pages I found quickly with that first
    search term will shed some light on the subject for you;

    easy isn't it?

    Thanks for pointing some good sources.

    And also to teach to look at google ( I also should allways include that
    when I answers some questions !!) :)

    There's also:

    I was hesiting between LS and HC, based on fact that I'm only hobist,
    Performance and speed needed for are ok with those, and cost seems to
    be nearly the same ...

    So I bought some LS for foulling around :)
