74LS86 Quad 2 Input Exclusive OR Gate IC

74LS86 Quad 2 Input Exclusive OR Gate IC is a widely used TTL (Transistor-Transistor Logic) integrated circuit designed to perform exclusive-OR logic operations with high speed and reliability. This IC contains four independent XOR gates, each capable of accepting two binary inputs and producing a single output. The output becomes HIGH only when the inputs differ, making it an essential component in digital electronics, computing systems, communication circuits, and embedded applications.

Built using Low-Power Schottky (LS) technology, the 74LS86 offers faster switching speeds and reduced power consumption compared to standard TTL logic devices. It is compatible with other 74LS series ICs, ensuring seamless integration into existing digital logic designs. Owing to its robustness and ease of use, this IC is commonly found in educational labs, industrial electronics, and commercial digital systems.

74LS86 Quad 2-Input Exclusive-OR (XOR) Gate IC contains four independent XOR gates, each performing a basic exclusive-OR logic function. Each gate accepts two binary inputs and produces a HIGH output only when the inputs are different—one HIGH and the other LOW. When both inputs are the same, either HIGH or LOW, the output remains LOW. Built using Low-Power Schottky (LS) TTL technology, the 74LS86 provides fast switching speed and low power consumption. It operates with a 5V supply and is commonly used in digital comparison, arithmetic, parity checking, and error detection circuits.

Working Principle

Each XOR gate inside the 74LS86 produces a HIGH output only when its two inputs are different (i.e., one input is HIGH and the other is LOW). When both inputs are the same (both HIGH or both LOW), the output remains LOW. This unique logic behavior makes XOR gates ideal for comparison, parity checking, and arithmetic operations.
