DESCRIPTION/ORDERING INFORMATION

The PCA9306 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin.

When EN is high, the translator switch is ON, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2

I/O, respectively, allowing bidirectional data flow between ports. When EN is low, the translator switch is off, and

a high-impedance state exists between ports.
