    I read some stoff on wikipedia.
    I'm wondering why they didn't use either TTL or ST for all pins...
    Moreover, do I need something special if it is TTL? Just a voltage of 5V, right?

    Read some more stuff on wikipedia on "hysteresis".
    Then some of the benefits and/or drawbacks of an ST input will become more clear...
