I have an XOR gate wired (74LS136) and I don't think it is working properly. Here is the table I think it should be outputting:
|X|Y||O| ------- |0|0||0| |0|1||1| |1|0||1| |1|1||0| 1 is a High 0 is a Low
I think this is the right output for the gate, but this is not what I'm getting. This is what I am getting out of my XOR gate:
|X|Y||O| ------- |0|0||0| |0|1||~| |1|0||~| |1|1||0| 1 is a High 0 is a Low ~ is nothing
When I probe the output pin I get neither a high nor a low, it says no current. I have tried a couple different chips from the same manufacturer but they all have the same result. Is this normal for an XOR gate? Is this chip suppose to be doing this? Am I using the wrong chip?
