About this product
The 74HC86 is a high-speed CMOS IC containing four independent 2-input exclusive-OR (XOR) gates. An output goes high only when its two inputs are different. It is used for data comparison, parity generation, error detection and simple adder or toggle logic in digital and educational circuits.

Frequently asked questions
What should I do with unused inputs on the 74HC86?
Tie unused inputs to GND or VCC. Do not leave CMOS inputs floating, because this can cause unstable outputs and extra power consumption.
Can one XOR gate be used as an inverter?
Yes. If one input is held high (VCC), the output is the inverse of the other input. Holding one input low passes the other input through unchanged.
