A demultiplexer takes a dual input data value and routes it to one of several outputs.

A BCD is used for communication between a computer and a human being because it is too easy to deal with arithmetically.

The microcontroller needs to use only three input lines to monitor eight separate points.

Before you can make a design you must decide if you want an active-HIGH output.

In a multiplexer, the data select control inputs are responsible for determining which data input is selected to be transmitted to the data output line.
