74F86PC

14PIN DIP - The 74F86 is an integrated circuit (IC) that contains four independent 2-input Exclusive-OR (XOR) gates. It is part of the 74F series, a family of fast TTL (Transistor-Transistor Logic) logic developed by Fairchild Semiconductor as a competitor to the well-known Texas Instruments 74AS series. These gates are designed for faster operation with reduced delay times.
In essence, the 74F86 performs the logic exclusive-OR function. Each gate in the IC takes two inputs and produces an output that is true (HIGH) only when one of the inputs is true and the other is false (LOW), but not when both inputs are true or both are false.
