7486 IC Quad 2-Input Exclusive-OR Gate
The IC 7486 consists of four independent XOR (exclusive-OR) gates, each with two inputs. Each gate outputs a logic HIGH only when its two inputs are at opposite logic levels—one HIGH and one LOW.
Engineers use the 7486 in digital systems that need logical comparison, such as parity generators, parity checkers, binary adders, and control logic. XOR gates are essential in many error detection and correction schemes due to their unique ability to identify input differences.
Each gate in the 7486 responds independently, making the IC versatile for parallel operations. The chip operates reliably within the TTL voltage range and integrates seamlessly into standard 5V logic systems. You can also cascade XOR gates to build more complex logic functions like multi-bit adders and comparators.
