Hi All

Do we have a capless RS232 transciever that runs from 3.3 volts?

Thanks

Jeff,

To generate RS232 drive levels requires boosting the 3.3V supply voltage. The power level required prevent using integrated capacitors. Therefore external capacitors or external higher voltage supplies are required.
