NE555

The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package. Introduced in 1972 by Signetics, the 555 is still in widespread use due to its low price, ease of use, and stability. It is now made by many companies in the original bipolar and in low-power CMOS technologies. As of 2003, it was estimated that 1 billion units were manufactured every year. The 555 is the most popular integrated circuit ever manufactured.

Silicon die teardown: a look inside an early 555 timer chip

“If you’ve played around with electronic circuits, you probably know the 555 timer integrated circuit,1 said to be the world’s best-selling integrated circuit with billions sold. Designed by analog IC wizard Hans Camenzind2, the 555 has been …

Understanding the 555 Timer IC

“I had a really difficult time understanding exactly what 555 timer circuits do and how they work. Most explanations online refer to their functionality when paired with RC series, but not exactly what logical interactions between the different input pins …
