If one but not both inputs are high 1a low output 0 results. There are two symbols for XOR gates: There are two symbols for XNOR gates: For example, the 74LVC1G microchip is advertised as a three-input logic gate, and implements a parity generator. If a logic gate were to accept three or more inputs and produce a true output if exactly one of those inputs were true, then it would in effect be a one-hot detector and indeed this is the case for only two inputs.
The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. Retrieved 6 May This is the main principle in Half Adders.
When offset by 5 bits, the sequence exactly matches its inverse. The result is a circuit that outputs a 1 when the number of 1s at its inputs is odd, and a 0 when the number of incoming 1s is even. Please help improve this daasheet by adding citations to reliable dxtasheet. This page was last edited on 19 Decemberat Pseudo-random number PRN generators, specifically Linear feedback shift registersare defined in terms of the exclusive-or operation.
Example half adder circuit diagram. Wikimedia Commons has media related to XOR gates. It does not implement a logical “equivalence” function, unlike two-input Exclusive OR gates; for example its output is L ow when all inputs are L ow. For the NOR constructions, the lower arrangement offers the advantage of a shorter propagation delay the time delay between an input changing and the output changing.
Views Read Edit View history. From Wikipedia, the free encyclopedia. The behavior of XOR is summarized in the truth table shown on the right. For daasheet NOR constructions, the upper arrangement requires fewer gates. It is most xof to regard subsequent dor as being applied through a cascade of binary exclusive-or operations: In other projects Wikimedia Commons. When searching for a specific bit pattern or PRN sequence in a very long data sequence, a series of XOR gates can be used to compare a string of bits from the data sequence against the target sequence in parallel.
This article is about XOR in the sense of an electronic logic gate e.

For XOR in the purely logical sense, see Exclusive disjunction. Note that the caret does not denote logical conjunction AND in these languages, despite the similarity of symbol. For more information see Logic Gate Symbols.

Introduction to Logic Gates
A way to remember XOR is “one or the other but not both”. Correlators are used in many communications devices such as CDMA receivers and decoders for error correction and channel codes. A slightly larger Full Adder circuit may be chained together in order to add longer binary numbers.
However, extending the concept of the binary logical operation to three inputs, the SN74S with two shared “C” and four independent “A” and “B” inputs for its four outputs, was a device that followed the truth table:. An XOR gate implements an exclusive or ; that is, a true output results if one, and only one, of the inputs to the gate is true.
Other uses include subtractors, comparators, and controlled inverters. Articles needing additional references from December All articles needing additional references Commons category link is on Wikidata. XOR gates produce a 0 when both inputs match. A high output 1 results if both of the inputs to the gate are the same.
In other projects Wikimedia Commons. The “Rss” resistor prevents shunting current directly from “A” and “B” to the output. If a specific type of gate is not available, a circuit that implements the same function can be constructed from other available gates. For other uses, see XOR disambiguation. XNOR gate circuit using three mixed gates.
A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function.
