2x4 Decoder Circuit Diagram. And four outputs represented by d0 d1 d2 d3 d4 d5 d6 and d7. One exception to the binary nature of this circuit is the 4 to 10 line decoder demultiplexer which is intended to convert a bcd binary coded decimal input to an output in the 0 9 range.
So if n represents given input lines then possible output lines would be 2 n. Thus each output of the decoder will be generated to the input combination. To construct a decoder we require to know the number of all possible output lines that totally depends on the given input.
Circuit design of 4 to 16 decoder using 3 to 8 decoder.
It can be 2 to 4 3 to 8 and 4 to 16 line configurations. The circuit is implemented with and gates as shown in the figure. The circuit diagram of 2 to 4 decoder is shown in the following figure. This type of decoder contains two inputs.
