Convert XOR gate to inverter. Can also act as binary switch.

Lets review the truth-table of XOR gate gain.

Input A Input B XOR
0 0 0
0 1 1
1 0 1
1 1 0

Now from above table its clear that if we tie either of INputs A or B to 1 the xor gate will act as inverted when passed through the circuit. 

Example Lets Tie Input A to 1, we have an inverter B below. Similiarly yuo can tie input B to 1 to get inverter A below. 

Input A Input B XOR
1 0 1
1 1 0
