The ATmega328P operates at 16MHz max.

I wondered about that too.

Why can't you invert with software? How is the square wave (PWM?) being generated. What is it synced to?

Even the lowly CD4069 can easily do that.

it is generated using arduino for power converter

is 7404 suitable ?

 

Taking a guess; do you need 2 signals out of phase with each other and that's why you want an inverter? It may be easier to just use 2 IO pins and invert one.

So? Why not do it in software? Are you writing the code or just cut and paste?

yes this is thae case, i want to generate a square wave with its complementary

Unfortunately , I am not a great coder. I looked for libraries to help but without any results

7404 is an order of magnitude faster than CD4069; it uses more power too.

 

Don't need to be the best coder don't need any libraries just use Port Manipulation
https://www.arduino.cc/en/Reference/PortManipulation

By using Port Manipulation you would use a delay to set 2 pins at the same time one high one low
the after time delay you change them Low to High not any hard coding to it.

Depending on your tolerance requirement, you can also use digitalWrite() to set each pin individually. That might be simpler for a beginner coder, and they'll be set only a few clock cycles apart which could be considered at the same time depending on your tolerance requirements:

digitalWrite(13, HIGH);
digitalWrite(12, LOW);

I don't know about Arduino, but with Microchip's PIC's you can just invert the clock (rather than rising edge, use falling edge or visa versa). It's just a matter of changing one bit.

 

is 7404 suitable ?

Yes. any version of a 7404 or 7414 that is rated to operate on 5 V will work.

Are you considering a "dead time" so both mosfets (?) are not on at the same time. That can be done in software, or there are chips that take a single PWM input and output complementary signals with deadtime.

 

Just building on the above; what is the purpose of the 50kHz signal? If it's for a SMPS or something similar, odds are there is an IC purpose built for it that may make for a better (and possibly easier) implementation.
