The XNOR gate is a digital logic gate whose function is the inverse of the exclusive OR (XOR) gate. The two-input version implements logical equality, behaving according to the truth table to the right. A HIGH output (1) results if both of the inputs to the gate are the same. If one but not both inputs are HIGH (1), a LOW output (0) results. A logic gate performs a logical operation on one or more logic inputs and produces a single logic output. ... The XOR gate is a digital logic gate that implements exclusive disjunction - it behaves according to the truth table to the right. ... XNOR Logic Gate Symbol Logical equality is a logical operator that corresponds to equality in boolean algebra and to the logical biconditional in propositional calculus. ...

Symbols

Hardware description and pinout

XNOR Gates are basic logic gates, and as such they are recognised in TTL and CMOS ICs. The standard, 4000 series, CMOS IC is the 4077, which includes four independent, two-input, XNOR gates. The pinout diagram is as follows: A Motorola 68000-based computer with various TTL chips. ... For other uses, see CMOS (disambiguation). ...

Alternatives

If no specific XNOR gates are available, one can be made from five NAND gates in the configuration shown below. In fact, any logic gate can be made from combinations of only NAND gates or only NOR gates. NAND gates have the property, along with NOR gates, to be able to be combined to form any other kind of logic gate. ... a simple NOR gate NOR gates have the property, along with NAND gates, to be able to be combined to form any other kind of logic gate. ...
