What happened to the NE555, the tiny timer chip that powered millions of electronic projects? For more than half a century, this simple 8-pin IC has blinked LEDs, generated tones, controlled motors, triggered alarms, and helped generations of hobbyists discover electronics.
Designed by Hans Camenzind and introduced by Signetics in the early 1970s, the NE555 timer chip became one of the most widely used integrated circuits ever created.
In this video, we explore how the 555 timer works, why engineers loved its simple and flexible design, and how it found its way into countless DIY electronics projects and commercial products.
We’ll also look at the weaknesses of the original design, the rise of CMOS versions, and how microcontrollers such as the ATtiny and Arduino gradually replaced the NE555 in many applications.
But unlike many technologies from its era, the NE555 never truly disappeared. More than 50 years later, versions of the legendary timer chip are still manufactured, sold, taught, and used on breadboards around the world.

Just outside of San Antonio, east of China Grove (as in the song)...

I ran an industrial electronics repair business for Southern Ohio, WV, and KY, where I repaired many drive circuit boards for several brands of welding machines and motor controls, and the 555 and 741 were used a lot. I bought them in bulk, fifty to a magazine tube, along with sockets if the boards didn't have them. Some call them jellybean parts.
