Interfacing (DSI, CSI, I2C, etc.) • Re: Are the two serial I/O pins 5v tolerant?

The bi-directional logic level converters are generally required for I2C where the same line changes direction.

As thagrol says, for simple serial you can use a potential divider for external TX to Pi RX, and check the datasheet of your external device RX for the lowest voltage it will accept as a logic high.
