Hello,
here's a little question about open colector and wired and.
Out = X Y
Question:
the output will be true when the circuit is closed (as in the figure) with the ground connections "closed". Is that correct?
Is the following correct?
 when they are all unconnected they dont send the 0 from the ground so the output gets the 1 from the Resistance
 when they are all connected they all send the 0 from the ground so the output is 0 because 0 goes above 1 in OC
 when one is connected it sends a 0 from the ground and the output is 0
Thanks.
