3 To 8 Decoder Circuit Diagram. D6 abc d7 abc. A 3 to 8 decoder has three inputs a b c and eight outputs do to d7.
A 3 to 8 decoder has three inputs a b c and eight outputs do to d7. 3 to 8 decoder logic diagram the logical diagram of the 3 8 line decoder is given below. From the above truth table of 3 lines to 8 line decoder the logic expression can be defined as.
The complement of input a 2 is connected to enable e of lower 2 to 4 decoder in order to get the outputs y 3 to y 0.
The truth table for 3 to 8 decoder is shown in table 1. From the truth table it is seen that only one of eight outputs do to d7 is selected based on three select inputs. 3 to 8 line decoder demultiplexer 4. Based on the 3 inputs one of the eight outputs is selected.
