74F266 (XNOR)

The XNOR logic gate only switches its output pins on when both inputs are in the same state. This means that both inputs should be high at the same time, or they both should be off at the same time for the gate to provide output. Although the XNOR gate can be built by making use of 1 OR gate, 2 AND gates and 2 inverters, this IC is compact and easy to use and will help to decrease the size and complicity of your circuit.

What makes this family of logic gates special is the enormous speed at which they operate. This allows for much faster processing on bigger circuits and much less delay between the input and output of the circuit.
