In this chapter we will look at combinational logic circuits. These are circuits that respond simply to the state of their inputs at that moment in time. They don’t care about what has happened before as with sequential logic circuits. There are a range of useful combinational logic circuits that make up the basis of devices today, and we will study how they work. They will include
The half adder
The full adder
The multiplexer
The Tri-state Buffer
Before we go too far into the world of combinational ...
