12. Using Logic ICs

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 ...

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
