Know Your IC seeks to demystify common Integrated Circuits and allows people to understand them to a point where they can use them in their own projects.
The first circuit in this series is the widely used 555 timer.
If you have suggestions for future chips we should cover, please shoot me an email!
I decided to make the layout pictures easier to read, i know it was confusing some people. I hope this helps!
Step 1: History Of The Chip
The 555 timer replaced 23 transistors, 15 resistors and 2 diodes and allowed manufacturers to use this problem solving method much easier.
Today with billions of the chips in exsistence, it is one of the most widely used chips. Most people who do electronics hear of the 555 timer first. It is the gateway drug to the world of integrated circuits.
