This bi-directional level converter makes use of the Texas Instruments TXS0108E chip, which performs bi-directional level shifting for a wide range of logic level voltages and will even auto-detect signal direction. The one thing that doesn’t work well with this chip in particular is I2C communication – the strong I2C pullups tend to confuse the auto-direction sensing circuitry. If you need to use pullups on your logic lines, we recommend keeping them above 50KΩ when possible. One last note – the TXS0108E does not have strong output pins that can drive LEDs or long cable runs, so we don’t recommend using it for these types of applications.
