a look at EXOR and EXNOR gates - the exclusive gates

a look at EXORs an EXNORs elektor may 1984 Most electronics hobbyists are now quite familiar with digital technology. We all know the most commonly used gates, like ANDs, ORs and NANDs, but the EXOR and EXNOR gates are probably not so well known. Those who are familiar with these two functions, however, know them as versatile, almost universal, gates. This article will look at just some of the many possible uses of these two important digital elements. a look at EXORs and EXNORs the exclusive gates In a two-input EXOR gate, the output is "1" if one and only one input is "1". A two- input EXNOR gate is the opposite; in this case the output is "1" if both inputs are either "1" or "0". It is all very well to look at the standard definition for a digital circuit, but very often this is little help is seeing how to use the device. Certainly this is the case with EXOR and EXNOR gates. These devices have three important uses: (a) inverting buffer (shown in figure la for EXOR and 2a for E...
