Anyone know of a USB to 2 Port serial IC (which works at 3.3v)?
The only one i can find close is FT2232D but it only works off a 5v supply
thanks
The FT2232 as well as other FT chips works at 5V with the USB engine, and those 5V are taken from USB connector. But if you connect VCCIOA and VCCIOB at 3,3v, then the data interfaces will work at 3,3V. I do not see why do you want it to work at 3,3v since you have 5V at the USB connector anyway.
