A while back I published a tutorial on the basics of logic gates. The tutorial talks about what logic gates are, truth tables, and active levels.
Then, the tutorial talks about the basic logic gates many of us are familiar with: NOT, AND, OR, NAND, NOR, XOR, and XNOR.
Because of limited space, the post did not cover Boolean algebra, DeMorgan’s theorems, combinational logic, etc. It also leaves out an important and practical part of digital design with gates – the electrical characteristics of logic gates.
This tutorial on logic gates will with leave the topics of Boolean algebra, DeMorgan, etc. for a future tutorial.
This time, we’re going to focus on the important and practical, yet often overlooked, electrical properties and characteristics of logic gates.
