This bi-directional level converter makes use of the TXB0108 chip. The chip performs bi-directional level shifting from pretty much any logic level voltage and will auto-detect the direction. The only thing that doesn’t work well with this chip is I2C (because it uses strong pullups which confuse the auto-direction sensor). If you need to use pullups, you can but they should be at least 50K Ohms – the ones internal to AVRs/Arduino are about 100K Ohms so those will work.

Since this chip is a special bi-directional level shifter, it does not have strong output pins that can drive LEDs or long cable runs so it shouldn’t be used for those kinds of applications.
