Four pin AND?

[ehsjr]

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----

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.

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