exclusiv NOR (XNOR)

The logical operator XNOR (Exclusive NOR) forms the complementary function to XOR

. The truth value of XNOR then has a "1" at the output if the input values are the same, regardless of whether "0" or "1".

The output is "0" if all the inputs are different. The truth table of XNOR corresponds to the negated truth table of XOR. The value table corresponds to the negated value table of the XOR gate. Circuit families for XNOR gates are the 74266 in TTL logic and 4077 in CMOS.
