    Clean square waves using a 555 timer?

    Xeno, I had the identical leading edge spike problems that you have described and found your posts while I was looking for a solution. I am using the 555 to generate a 10kHz sqr wave and driving a 10K resistive load. I didn't care why the 555 has the spike, just how to get rid of it. My fix...
