I was experimenting with logic gates on my breadboard and tried a 3-input logic gate.

I got the following result:

Input  |  Output
A B C  |   ?
0 0 0  |   1
0 0 1  |   0
0 1 0  |   1
0 1 1  |   0
1 0 0  |   1
1 0 1  |   0
1 1 0  |   1
1 1 1  |   1

What logic gate could this be? Thanks

  • \$\begingroup\$ @Transistor sorry, what do you mean part number and pinout? I've built a transistor logic gate if that helps... \$\endgroup\$ Jul 1, 2017 at 9:18
  • \$\begingroup\$ @Andyaka oh! Is there a specific name given to this function \$\endgroup\$ Jul 1, 2017 at 9:19

    \$\begingroup\$ @Mi hirChaturvedi: When you said "... and tried a 3-input logic gate" I read it as you were probing one gate. I think you have created some combinational logic rather than a logic "gate". \$\endgroup\$

Functionally it is this: -

And it doesn't have a specific name unless someone somewhere in some obscure place has named it.

  • \$\begingroup\$ Thanks! It does output exactly the same values. How did you figure it out though? \$\endgroup\$ Jul 1, 2017 at 11:21
  • \$\begingroup\$ The output is the inverse of C except for one instant. \$\endgroup\$
