2-Bit Binary Decoder

Cuthbert Nyack
A simple application of a digital electronics combination circuit is shown below. It is a 2 bit binary decoder implemented with inverters and NOR gates. Input consists of 2 binary bits A and B. There are 4 outputs, one for each of the 4 possible combinations of AB(00 01 10 11). The states of A and B can be changed by clicking on the rectangular areas marked click. Blue corresponds to LOW and red to HI.





In applet below the same circuit is implemented with inverters and NAND gates. In this case the output is normally HI and goes LO when activated.
