4 To 16 Decoder Using 2 To 4 Decoder Without Enable. 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. Construct 4 16 decoder using two 3 8 decoders.
4 to 16 decoder. These are the higher four min terms. It can be 2 to 4 3 to 8 and 4 to 16 line configurations.
We know that 3 to 8 decoder has three inputs a 2 a 1 a 0 and eight outputs y 7 to y 0.
We will see the cascading of decoders 3 8 using 2 4 4 16 using 3 8. We know that 3 to 8 decoder has three inputs a 2 a 1 a 0 and eight outputs y 7 to y 0. Construct 4 16 decoder using two 3 8 decoders. When two 3 to 8 decoder circuits are combined the enable pin acts as the input for both the decoders.
