Additional Details:

The 74VHC86 consists of four independent 2-input exclusive-OR gates. The output of each gate is HIGH when the two inputs are at different logic levels, and LOW when the two inputs are at the same logic level. This makes it ideal for applications requiring comparison or parity checking.

This XOR gate is commonly used in digital circuits for a wide range of applications due to its speed, low power consumption, and ease of use. It's particularly useful in error detection and correction circuits.
