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.
