2 1 Multiplexer Circuit Diagram. The demux will work only when the enable is set to logic 1. Design truth table logical expression circuit diagram for it.
Now the logical diagram for a 2 1 mux shows that we need two and gates one or gate and one not gate. 16 1 multiplexer using 8 1 and 2 1 multiplexer. It also has an enable input.
The multiplexer used for digital applications also called digital multiplexer is a circuit with many input but only one output.
The figure below shows the block diagram of a 2 to 1 multiplexer which connects two 1 bit inputs to a common destination. We can implement the 16 1 multiplexer using a lower order multiplexer to implement the 8 1 multiplexer we need two 8 1 multiplexers and one 2 1 multiplexer the 8 1 multiplexer has 3 selection lines 4 inputs and 1 output the 2 1 multiplexer has only 1 selection line. 16 1 multiplexer using 8 1 and 2 1 multiplexer. The input a of this simple 2 1 line multiplexer circuit constructed from standard nand gates acts to control which input i 0 or i 1 gets passed to the output at q.
