The 7486 / 74HC86 is a high-speed CMOS device containing four independent 2-input XOR gates. The Exclusive-OR function is the foundation of digital arithmetic. It is the core component used to perform binary addition (Sum bit) and is widely used in phase detectors and signal-comparison circuits.
The 74HC86 variant is the modern choice for students, offering the same functionality as the classic TTL 7486 but with much lower power consumption and a wider voltage range (2V to 6V), making it perfectly compatible with Arduino and Raspberry Pi GPIO levels.
Key Features
Quad XOR Capability: Four separate Exclusive-OR gates in a single 14-pin IC.
Arithmetic Ready: Specifically designed for building Adders, Subtractors, and Comparators.
CMOS Efficiency: Low power consumption with high-speed switching transitions.
Robust Logic: High noise immunity and stable output, even in complex breadboard environments.
