   conico:  You are trying to get the TL494 to work at 1MHz to 2 MHz, for the Kacher circuit?   The TL494IN work to 200KHz, The Texas Instrument TL494 is the best one to buy, and works to 300KHz,  but not 1 to 2MHz.

The one I tested at 1mhz the square wave was a lovely cone shape

NickZ, if you have 100 picoF cap in pin 5 of texas instruments TL494, it will work at 2Mhz,
or maybe I'm talking to a 12-13 years old kid. If you want to know, learn and work.

if you want to go further than 1.1Mhz with that TL494, power it by 9v or 6v, it will increase in frequency.

Yes, It sounds little bit to much for TL494.

But, never tried to force it to those frequencies.

I used SG3525  100Hz - 500kHz, it has totem-pole outputs.

And I stayed with SG3525, very cheap and simple chip, duty 0-50% same as TL494.

And is pretty stable.

I just looked at it's max frequency, and saw that is not specified, so, maybe is possible to drive it faster.

Probably same is with TL494 and TL494 can be driven faster than specified?

   I try to help you out, and get insults. Ok, no problem. Sorry I asked.

No not realy I can do the same with a 4093 for test set up experiments  at 1.7mhz it's ris time is 22ns and fall is 10ns
but i'm using a SG as input and no smit witch will slow it down but what does that matter if you use Sharks trick 

OK lets assume we feed a square wave (lets use 1.8mhz  as it adds up to 9) into an 'not gate' like a 4093 (pins 1&2 linked, now if we feed it's output into a cap and it's output into a another not gate but also on that same second (not gate) we hook up a variable resister with the other end down to the 4093's 0 volt line.

Now if we put a scope on the cap resistor connection we will see a triangle wave and as we vary the resistor we notice the slope will trigger
the 4093 out put position therefore adjusting the outputs pulse width.

If we think about it we can use this idea to our advantage.
