It will work? Or I would like to know if the logic converter also works as an alternative to avoid modify the...

zz0.8tpitu4y0i8zzI bought a ch341a (I'm waiting for it to arrive) and I noticed that the programmer has a bug that the data pins go to 5v when the VCC pin is at 3.3v (which is the voltage I'm looking for).

Instead of doing the 3.3v mod, I'm thinking of converting the 5v to 3.3v with an 8 channel TXS0108E through the ZIF socket but I don't know if that would work, because it has to circulate voltage and also information.

What I am looking for is something that will convert from 5v to 3.3v but without modifying the ch341a.

I can't buy the ch341a 1.6v that has...
