Working Principles

The TLC339MDG4 is a voltage comparator that compares the voltage at the non-inverting input (IN+) with the voltage at the inverting input (IN-). The output of the comparator switches depending on the relative voltage levels at these inputs. It operates by amplifying the voltage difference between the inputs and driving the output to either the positive supply voltage or the negative supply voltage.
