In digital electronicsa binary decoder is a combinational logic decocer that converts binary information from the n coded inputs to a maximum of 2 n unique outputs.

Binary decoder

They are used in a wide variety of applications, including data demultiplexingseven segment displays, and memory address decoding. There are several types of binary decoders, but in all cases a decoder is an electronic circuit with multiple input and multiple output signals, which converts every unique combination of input states to a specific combination of output states.

In addition to integer data inputs, some decoders also have one or more “enable” inputs. When the enable input is negated disabledall decoder outputs are forced to their inactive states. Depending on its function, a binary decoder will convert binary information from n input deoder to as many as 2 n unique output signals. Some decoders have less than 2 n output lines; in such cases, at least one output pattern will be repeated for different input values.

Decodeg binary decoder is usually implemented as either a stand-alone integrated circuit IC or as part of a more complex IC. In the latter case the decoder may be synthesized by means of a hardware description language such as VHDL or Verilog. Widely used decoders are often available in the form of standardized ICs.

A 1-of-n binary decoder has n output bits. This type of decoder asserts exactly one of its n output bits, or none of them, for every integer input value. The “address” bit number of the activated output is specified by the integer input value. For example, output bit number 0 is selected when the integer value 0 is applied to the inputs.

Code translators differ from 1-of-n decoders in that multiple output bits may be active at the same time. An example of this is a seven-segment decoderwhich converts an integer into the combination of segment control signals needed to display the integer’s value on a seven-segment display digit.

One variant of seven-segment decoder is the BCD to seven-segment decoderwhich translates a binary-coded decimal value into the corresponding segment control signals for input integer values 0 to 9.
