4 To 16 Decoder Truth Table. For each combination of inputs when the enable e is set to 1 one of these four outputs will be 1. So for instance i built my circuit and it went from 0000 1111.
2 to 4 line decoder. For each combination of inputs when the enable e is set to 1 one of these four outputs will be 1. The device features two input enable e0 and e1 inputs.
Decoders are used in digital systems whenever it is necessary to change from one code to another.
One of these four outputs will be 1 for each combination of inputs when enable e is 1. The truth table of 2 to 4 decoder is shown below. A binary code applied to the four inputs a to d provides a low level at the selected one of sixteen outputs excluding the other fifteen outputs when both the strobe inputs g1 and g2 are held low. Here the outputs y0 to y7 is considered as lower eight minterms and the output from y8 to y16 is considered as higher eight minterms.
