Transmission Gate XOR” p. However, this approach requires five gates of three different kinds.

Introduction to Logic Gates – XOR of 11 – Hardware Secrets

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. A high output 1 results if both of the inputs to the gate are the dafasheet. Here is a diagram of a pass transistor logic implementation of an XOR gate. The “Rss” resistor prevents shunting current directly from “A” and “B” to the output.

There are two symbols for XOR gates: XOR gates produce a 0 when both inputs match. By using this site, you agree to the Terms of Use and Privacy Policy.

Introduction to Logic Gates

If a specific type of gate is not available, a circuit that implements the same function can be constructed from other available gates. From Wikipedia, the free encyclopedia.

This article needs additional citations for verification.

Since the trailing sum bit in this output is achieved with XOR, the preceding carry bit is calculated with an AND gate. For other uses, see XOR disambiguation. The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. This is the main principle in Half Adders. Pseudo-random number PRN generators, specifically Linear feedback shift registersare defined in terms of the exclusive-or operation.


There are two symbols for XNOR gates: A way to remember XOR is “one or the other but not both”.

74LS86 Datasheet

It is most common to regard subsequent inputs as being applied through a cascade of binary exclusive-or operations: December Learn how and when to remove this template message.

Note that the caret does not denote logical conjunction AND in these languages, despite the similarity of symbol. A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. Datasheets are readily available in most datasheet databases and suppliers. XNOR gate circuit using three mixed gates.

This page was last edited on 19 Decemberat XOR represents the inequality function, i. This article is about XOR in the sense of an electronic logic gate e.

XOR gate circuit using three mixed gates. Other uses include subtractors, comparators, and controlled inverters. If one but not both inputs are high 1a low datsheet 0 results.

Articles needing additional references from December All articles needing additional references Xorr category link is on Wikidata. Strict reading of the definition of exclusive oror observation of the IEC rectangular symbol, raises the question of correct behaviour with additional inputs.

For example, if we add 1 plus 1 in binarywe expect a two-bit answer, 10 i. Wikimedia Commons has media related to XOR gates. In this example, the best match occurs when the target sequence is offset by 1 bit and all five bits match. For the NAND constructions, the upper arrangement requires fewer gates.

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. For example, the 74LVC1G microchip is advertised as a three-input logic gate, and implements a parity generator. For more information see Logic Gate Symbols. Hence, a suitable setup of XOR gates can model a linear feedback shift register, in order to generate random numbers.

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.

Longer sequences are easier to detect than short sequences. Datasheet from ” https: For the NOR constructions, the upper arrangement requires fewer gates.
