Xor Ic Pin Diagram. It will give the output of the second xor gate. It will use to make the common ground with power supply and other devices.
Circuit diagram and working explanation. The number of gates per ic varies depending on the number of inputs per gate. So when the button is pressed the corresponding pin of gate goes high.
Pin 5 will also use as the second input pin for the second xor gate in the ic.
So with two buttons we can realize the truth table of ex or gate. The truth table of an xor gate is given below. Circuit diagram and working explanation. Xor gate sometimes eor or exor and pronounced as exclusive or is a digital logic gate that gives a true 1 or high output when the number of true inputs is odd.
