The 74HC86D.653 is a 4-input XOR gate from Nexperia. It has two sets of inputs, A and B, and one output (Y). The output will be high only when one of the inputs A and B is at a high state and the other is at a low state. This device has excellent noise immunity, low power consumption and high-speed performance, making it suitable for a wide range of applications including computing, logic systems, and communications systems. It uses a CMOS logic compatibility and is housed in a 6-Lead SOT23 (SC-70) package with a Pb-free terminal finish.
