    Is there a 4 pin AND chip available?
    Something like this:

    +12 -----+
    |
    [R] (external)
    |
    +--- out
    |
    -----o----
    | | |
    | /c |
    inA o---| |
    | \e |
    | | |
    | | |
    | /c |
    inB o---| |
    | \e |
    | | |
    -----o----
    |

  2. That would be a NAND gate, eh? And I imagine you'd want some base
    resistors in most cases.


    There are very small gates like the following:

    Or you could probably cob something together with a 6-pin transistor
    array..

    a dual digital smt transistor?

    Yes NAND - it would be nice if the base resistors were in
    the chip, but not required. Requirements changed from
    "when signal is present" to "when signal is present and
    clock is high" - the prototype was already made. Grumble.

  5. Eg. Panasonic XP0431500L w/10K resistors, about 2mm square, but the
    TC7SZ00 is cheaper.
