In Chapter 11, we worked with our first integrated circuit, the LM393 voltage comparator. In this chapter, we are going to look at other ICs and talk more about how they are named and used in electronics.

12.1 Logic ICs

One of the easiest class of ICs to use are the logic ICs. A logic IC is a chip that implements a basic function of digital logic. In digital logic, electric voltages are given meanings of either “true” or “false,” usually with “false” being a voltage near zero and “true” being a positive voltage (often between 3 and 5 volts). These values are also referred to by a number ...
