    How fast do you need? They will all work to 25 MHz and many a lot higher.

    this is an excellent guide; http://www.i9t.net/vl/Logic Family.pdf

    Some have good propogation delays but slow rise/fall times and vice
    versa.

    At a quick around the net, FASTr is the best among TTL. I'd say that
    AC is a good compromise. ECL is also excellent. New and growing
    technology like this may be hard to find though.

    refer to the thread in this group of 11 Sep 2003 "All IC families"
