The TXS0101 can be used in level-translation applications for interfacing devices or systems operating at
different interface voltages with one another. The TXS0101 is ideal for use in applications where an open-drain
driver is connected to the data I/Os. The TXB0101 can also be used in applications where a push-pull driver is
connected to the data I/Os, but the TXB0102 might be a better option for such push-pull applications.
The TXS0101 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.
