74LS86

The 74LS86 is a versatile integrated circuit belonging to the 74LS (Low-power Schottky) family of TTL (Transistor-Transistor Logic) chips. It contains four independent 2-input XOR (exclusive OR) gates. Each gate has two inputs and one output. The output of an XOR gate is high (logic 1) if and only if its two inputs are at different logic levels. Conversely, the output is low (logic 0) if both inputs are at the same logic level. This functionality makes the 74LS86 useful in a variety of digital logic applications, including arithmetic circuits, error detection, and data scrambling. The "LS" designation indicates it uses low-power Schottky transistor technology, offering a balance between speed and power consumption compared to standard TTL devices. The chip typically comes in a 14-pin dual in-line package (DIP). It operates from a standard TTL power supply voltage, usually 5 volts.
