TXB0108 is a High-Speed, Full-Duplex 8-Channel Level Conversion IC.
It provides two-way communication capabilities between different logic levels.
Side “A” supports voltages of 1.2V to 3.6V, side “B” supports voltages of 1.65V to 5.5V.
Therefore, the level shifter can be used for all possible logic levels between 1.2V and 5.5V.
The TXB0108 is designed for push-pull outputs, not for open-drain. For open-drain applications like I2C for example, you are better off with the TXS0108E (also available in our shop).
