Bill, the 555 Schmitt trigger doesn't invert. You should delete the output bubbles in your tutorial.
How about an inverter? (4049)HI , Im working with some cmos
I got this signal I wanna invert , I wanna use something else than an 16 pin NOR gate .
Is there a smaller/faster component to use here ?
Darn that bear.Sorry, but you are wrong in this. It has been verified experimentally.
The hysteritic oscillator couldn't work if this were so, also verified experimentally.
