The PCA9306 device is a dual bidirectional I 2C and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.2-V to 3.3-V V REF1 and 1.8-V to 5.5-V V REF2.
The PCA9306 device allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin. The low ON-state resistance (R ON) of the switch allows connections to be made with minimal propagation delay. 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.
In addition to voltage translation, the PCA9306 device can be used to isolate a 400-kHz bus from a 100-kHz bus by controlling the EN pin to disconnect the slower bus during fast-mode communication.
