It is very common to use logic gates from one of two families of digital ICs: TTL and CMOS. Very Large-scale Integration consists of transistors from hundreds to several billion in number. In this kind of integrated circuits, the interconnections of the active, the passive, and discrete components on a silicon chip can be formed. For example, Figures 4 and 5 show the RTL (Resistor-Transistor Logic, which indicates that the electronic input of the circuit is a resistor and the output device is a transistor) and TTL (Transistor-Transistor Logic, which indicates that the input and the output of the circuit are transistors) structures of the NAND function. These logic gates work with binary input data or digital input data, such as 0 (low or false or logic 0) and 1 (high or true or logic 1). The comparator ICs are used as comparators for comparing the inputs and then to produce an output based on the ICs’ comparison. These ICs are simply the combination of integrated as well as separate components and these ICs have related characteristics and appearance apart from the way of film deposition. Integrated circuits can be defined as: Integrated circuits (ICs) are, much as their name would suggest, small circuits integrated into a plastic holder/"chip."
