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.
The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. Strict reading of the definition of exclusive oror observation of the IEC rectangular symbol, raises the question of correct behaviour with additional inputs.
A correlator looking for in the data sequence would compare the incoming data bits against the target sequence at every possible offset while counting the number of matches zeros:. Hence, a suitable setup of XOR gates can model a linear feedback shift register, in order to generate random numbers.
By looking at the datasheft between the number of ones and zeros that come out of the bank of XOR gates, it is easy to see where the sequence occurs and whether or xatasheet it is inverted.
For other uses, see XOR disambiguation. Both include four independent, two-input, XNOR gates.

However, it is rarely implemented this way in practice. Datasheets are readily available in most datasheet databases and suppliers.
The behavior of XOR is summarized in the truth datashet shown on the right. In this example, the best match occurs when the target sequence is offset by 1 bit and all five bits match. Note that the caret does not denote logical conjunction AND in these languages, despite the similarity of symbol.

XOR gate – Wikipedia
For the NOR constructions, the upper arrangement requires fewer gates. XOR represents the inequality function, i. For example, if we add 1 plus 1 in binarywe expect a two-bit answer, 10 i. Pseudo-random number PRN generators, specifically Linear feedback shift registersare defined in terms of the exclusive-or operation.
This is the main principle in Half Adders. For example, the 74LVC1G microchip is advertised as a three-input logic gate, and implements a parity generator. XOR gates produce a 0 when both inputs match. However, this approach requires five gates of three different kinds. From Wikipedia, the free encyclopedia. Longer sequences are easier to detect than short sequences. This page was last edited on 24 Octoberat 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.
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:.
It is datxsheet common to regard subsequent inputs as being applied through a cascade of binary exclusive-or operations: The “Rss” resistor prevents shunting current directly from “A” and “B” to the output. For the NAND constructions, the lower xo offers the advantage of a shorter propagation delay the time delay between an input changing and the output changing. In other projects Wikimedia Commons. As a result, XOR gates are used to implement binary addition in computers.
December Learn how and when to remove this template message. A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. Correlators are used in many communications devices such as CDMA receivers and decoders for error correction and channel codes.
