74HCT86 Quad 2-input XOR Gate
The 74HCT86 is a high speed CMOS Logic quad 2-input XOR Gate. 74HCT86 contain four independent EOR gates in one package. Logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption. It is commonly used in buffer circuits, controlled inverter circuits etc.

2-Input XOR Gate Truth Table:
Output acts based on the truth table which is given below. Let us consider the XOR logic with two inputs A, B and the output as Y. The output (Y) of XOR gate is 1 when both inputs (A, B) are different, and is 0 when both the inputs are the same.

How to Use 74HCT86 IC
TO use the 74HCT86 XOR Gate IC, just power it using the Vcc (pin 14) and ground (pin 7) lines. The typical operating voltage of the IC is +5V. The output voltage of the IC on the pin Y will be equal to the operating voltage of the IC. As per the XOR truth table shown above, the output of XOR gate will be 1 when both inputs (A, B) are different, and will be 0 when both the inputs are the same. The XOR gates are also called as EOR Gates or EXOR Gate. Working of the XOR Logic Gate is shown in below GIF image:
