The HD74LS86P is a quad 2-input XOR (exclusive OR) gate integrated circuit (IC) from the LS (Low Power Schottky) series of logic gates. It contains four individual XOR gates, each capable of taking two binary inputs and producing an output that is true if and only if one of the inputs is true, but not both. The IC is commonly used in digital electronics for tasks involving comparison, arithmetic, and data manipulation. With a low power consumption and high-speed performance, it is widely used in applications such as digital signal processing, data encoding/decoding, and error detection systems. The HD74LS86P is available in a standard 14-pin dual in-line package (DIP), making it compatible with most breadboards and circuit designs.
