3 To 8 Decoder. The below is the pin configuration for the ic74hc238 3 to 8 line decoder or demultiplexer. In this section let us implement 4 to 16 decoder using 3 to 8 decoders.
3 8 decoder explanation digital decoder encoder and decoder decoder circuit receiver set top box decoder and encoder dcc decoders ho encoder and decoder in d. Vhdl program simulation waveforms as shown in the figure the input output waveforms look similar to the decoder because the encoder is just the reverse of the decoder. When two 3 to 8 decoder circuits are combined the enable pin acts as the input for both the decoders.
Decoder with three inputs would give 8 outputs n 2 2 3 that is 8.
The number of available inputs are 3 and outputs are 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. Here are the steps to. Features of 74hc238 ic.
