What a sad day.

Rest in Peace Hans.

    That ain't old!

    I'm using 556s in IR beacons at home right now. RIP Hans, and thank you.

    Wow, I wonder if he had any idea when he invented it what it would turn into?

    Guess you never really know the value of your t = ln(2)R2C1, so live each day like it's your last!

    RIP and thanks!

    I wonder if he ever imagined the 555 would find so many uses over the years.

    Most of my heroes are gone, but not forgotten.

    At least, being older than Chip, I will not have to read his obituary, and wonder would could have been...

    How many have found the 555 so easy to use and inspired so many circuits that now end up on one chip, A great loss but will go down in history, The only shame is will future generations even know of the 555?

    According to the eetimes article, he also
    introduced the concept of phase-locked loop to IC design
    ,
    something I didn't know. That's quite profound.

    A long time ago I was paranoid they would stop making the 555 lol...

    555 timer brings up 720,000 hits on Google. How many can claim an influence so profound? Hans, we hardly knew ye, but thanks for the 555, and all the best to your family! Your legacy lives on, embodied in silicon!

    Oh, how sad. My respects - like many others, the 555 was one of my first forays into building things with ICs.

    His book, Designing Analog Chips 2005 edition is a free download, a very accessible exposition of integrated circuit technology.

    Understanding how the 555 works is in and of itself a great starting point for a well rounded EE education.

    I'd been using the 555 for years but it was a while before I was confused by hearing it referred to as the "triple nickel". I used it in the conductivity measurement circuit for "Earth Measurements" in Stamps in Class.

    RIP

    Too bad, another loss of another great analog designer. The free book is a GREAT read, bridging the gap between between the Forest Mims style cookbook type books (childhood favorites) and EE books that begin page 1 full of equations.

    It is an analog world when you get down to it after all.

    Yeah. And then when you get really down to it, it gets all discrete again. Think elementary particles, quantum states etc.

    +1, and the early history of semiconductors and the Shockley/Bell/Fairchild drama adds some liveliness to the very useful but comparatively dry tech info that follows!

    Thank you Tracy for sharing that link.
