A DMUX is the opposite of MUX. It recieves one input and based on the value of the selector bit, it routes that input to one of two output lines.
Looking at the image above, if sel is 0, then the value of 'in' will be routed to O0, and if sel is 1, then the value of 'in' will be routed to O1.
To achieve this, we can AND 'in' with '`sel', sending that output to O0. We also AND 'in' with 'sel', sending that output to O1.
