The TXS0104E can be used in level-translation applications for interfacing devices or systems operating at

different interface voltages with one another. The TXS0104E is ideal for use in applications where an open-drain

driver is connected to the data I/Os. The TXS0104E can also be used in applications where a push-pull driver is

connected to the data I/Os, but the TXB0104 might be a better option for such push-pull applications.

The TXS0104E architecture (see Figure 1) does not require a direction-control signal to control the direction of

data flow from A to B or from B to A.
