3 To 8 Decoder With Enable. The verilog code for 3 8 decoder with enable logic is given below. The block diagram of 3 to 8 decoder using 2 to 4 decoders is shown in the following figure.
Decoder in this tutorial you learn about the decoder which is one of the most important topics in digital electronics in this article we will talk about the decoder itself we will have a look at the 3 to 8 decoder 3 to 8 line decoder designing steps a technique to simplify the boolean function and in the end we will draw a logic diagram of the 3 to 8 decoder. The input a 2 is directly connected to enable e of upper 2 to 4 decoder in order to get the outputs y 7 to y 4. 74hct138 features three enable inputs.
The input a 2 is directly connected to enable e of upper 2 to 4 decoder in order to get the outputs y 7 to y 4.
The verilog code for 3 8 decoder with enable logic is given below. 74hct138 decoder accepts three binary weighted address inputs a0 a1 and a3 and when enabled provides 8 mutually exclusive active low outputs y0 to y7. When two 3 to 8 decoder circuits are combined the enable pin acts as the input for both the decoders. For a 3.
