An example of level translation circuitry of this kind is:
The
example is
done with a SIPEX SP3282EB RS232 Transceiver that could accept supply voltages lower than
3V DC.
NOTE:
In this case Vin has to be set with a value compatible with the logic levels of the module. (Max
2.9V DC). In this configuration the SP3282EB will adhere to EIA/TIA-562 voltage levels
instead of RS232 (-5 ~ +5V).
