TXB010x VS TXS010x
For the same reason, the TXB0108 should not be used in applications such as I2C or 1-Wire where an open-drain driver is connected on the bidirectional data I/O. For these applications, use a device from the TI TXS01xx series of level translators.
Type | Open-Drive | Push-pull | Examples |
