How good are my chances of getting accepted for direct PhD programs in the electronics or communications field?

There are a lot of problems with the question. You may want to reconsider how you’ve asked it.
 
So you’ve cleared your backlogs? Then why do you still refer to them?
 
The 68% is not impressive. The two papers might be impressive, but that will depend on where they were published and with whom you published. Better PhD programs are looking for A students (94%). PhDs are not that hard to get anymore so you really need to evaluate why you want one. Do you want to do research or do you want the initials?
 
You refer to integrated PhD and direct PhD. It will depend on the department you choose. Many departments allow for a the terminal masters, but others simply do not have an option for that – you get your PhD or you get nothing. But it depends on the department and the school. You should know that if you’re at a university in the US pursuing a degree.
 
Did you perhaps mean integrated as in multi-discipline? That is not how you’ve asked it.
 
Electronics OR Communication ?
 
In the US we view those fields VERY differently.
 
If you have a bachelor degree granted by a US accredited program, your chances of admission to a a US PhD program are better than the equivalent degree from outside the US.
 
But!
 
If you apply to a PhD program of any merit in the US, your competition will be strong students within the US and strong students from outside the US.
 
If you were to have earned your current degree in another country, your chance for admission would be less than if you earned that same degree in the US.
 
Based on your lack of academic understanding and poor communication, I’d say that a PhD program that accepts you is probably not one you want to attend. Save your money and build your professional skills.
