This decoder circuit offers 8 logic outputs for 3 inputs and has a enable pin.. Fig.4 Functional diagram. Fig.5 Logic diagram (one decoder/demultiplexer). September 1993 5 Philips Semiconductors Product specification Dual 2-to-4 line decoder/demultiplexer 74HC/HCT139 AC WAVEFORMS PACKAGE OUTLINES See “74HC/HCT/HCU/HCMOS Logic Package Outlines”.. n to 2 n Decoder. The logic diagram of a 2-to-4 decoder is shown. The two data inputs are decoded into 4 outputs , each output representing one of the combinations of the two binary input variables .Where required the inputs are inverted and each of the AND gates generates one.

In a similar fashion a 3-to-8 line decoder can be made from a 1-to-2 line decoder and a 2-to-4 line decoder, and a 4-to-16 line decoder can be made from two 2-to-4 line decoders. You might also consider making a 2-to-4 decoder ladder from 1-to-2 decoder ladders..
