Hans Camenzind, Inventor of the 555, dies.

From EE Times:

Hans Camenzind, the Swiss emigre analog guru who invented one of the most successful circuits in electronics history and introduced the concept of phase-locked loop to IC design, passed away in his sleep at the age of 78. The news was reported today (Aug. 15) by Sergio Franco, an emeritus professor of electrical engineering at San Francisco State University in an email.

Camenzind came to the United States in 1960 and worked for several years at some of the storied names of the newly developing semiconductor industry: Transitron, Tyco Semiconductor, and Signetics.

In 1971 he joined the ranks of entrepreneurs by founding InterDesign, a company specializing in semi-custom integrated circuit design. It was there, working under a contract with Signetics, that he invented the 555 timer.  Signetics commercialized the device in 1972, and it went on to become one of the most successful in the industry’s history. The device, used in oscillator, pulse-generation and other applications, is still widely used today. Versions of the device have been or are still made by dozens of major semiconductor vendors, including Texas Instruments, Intersil, Maxim, Avago, Exar, Fairchild, NXP and STMicroelectronics.

Camenzind also introduced the idea of phase-locked loop to design and invented the first class D amplifier.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter

  1. Mr. Camenzind was not only an analog genius, but willing to help out the electronics community: he and Forrest Mims were the two final judges for the 555 Design Contest set up last year by Jeri Ellsworth and Chris Gammell. It was very cool that such a legend would provide his time and expertise to help out like that. He will definitely be missed.

  2. Ah heck.
    and Harry Harrison too.
    The first chip I ever used was the NE 555, and I still have fond memories of a crowded store (cavern more like) in Akihabara that sold 555s en masse, with a scoop for the customer to pour them into their ziploc baggies.

    A fine little chip. And I doff my hat to the 556 as well.
