Wikimedia Commons has datasneet related to XOR gates. A high output 1 results if both of the inputs to the gate are the same. The “Rss” resistor prevents shunting current directly from “A” and “B” to the output. Unsourced material may be challenged and removed. For the NAND constructions, the upper arrangement requires fewer gates.

Retrieved 6 May If one but not both inputs are high 1a low output 0 results. A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function.

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. It does not implement a logical “equivalence” function, unlike two-input Exclusive OR gates; for example its output datashret L ow when all inputs are L ow.

XOR can also be viewed datashert addition modulo 2.

XOR gate – Wikipedia

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. For XOR in the purely logical sense, see Exclusive disjunction.


For the NOR constructions, the upper arrangement requires fewer gates. For example, if we add 1 plus 1 in binarywe expect a two-bit answer, 10 i. However, extending the concept of the binary logical operation to three inputs, the SN74S with two shared “C” and four independent “A” and datasueet inputs for its four outputs, was a device that followed the truth table:.

XOR gates produce a 0 when both inputs match.

Datasheets are readily available in most datasheet databases and suppliers. This article is about XOR in the sense of an electronic logic gate e.

An engineering approach to digital design. If a specific type of gate is not available, a circuit that datadheet the same function can be 786 from other available gates.

Introduction to Logic Gates

When offset by 5 bits, the sequence exactly matches its inverse. Strict reading of the definition of exclusive oror observation of the IEC rectangular symbol, raises the question of correct behaviour with additional inputs.

Other uses include subtractors, datsheet, and controlled inverters. The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. 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:. This makes it practically useful as a parity generator or a modulo-2 adder.

There are two symbols for XNOR gates: The two-input version implements logical equalitybehaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. The behavior of XOR is summarized in the truth table shown on the right. In other projects Datsaheet Commons. Both include four independent, two-input, XNOR gates. Retrieved from ” https: Retrieved from ” https: The number of 0 outputs can then be datashert to determine how well the data sequence matches the target sequence.


XOR represents the inequality function, i. Longer sequences are easier to detect than short sequences. Datashwet a logic gate were to accept three or more inputs and adtasheet 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, it is rarely implemented this way in practice. For example, the 74LVC1G microchip is advertised as a three-input logic gate, and implements a parity generator.

From Wikipedia, the free encyclopedia. As a result, XOR gates are used to implement binary addition in computers. 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. Please help improve this article by adding citations to reliable sources. A way to remember XOR is “one or the other but not both”. It is most common to regard subsequent inputs as being applied through a cascade of binary exclusive-or operations: The “Rss” resistor also limits the current from Vdd to ground which protects the transistors and saves energy when the transistors are transitioning between states.
