This dual bidirectional I2C and SMBus voltage-level translator, with an enable (EN) input, is operational from 1.2-V to 3.3-V VREF1 and 1.8-V to 5.5-V VREF2.

The PCA9306-Q1 allows bidirectional voltage translations between 1.2 V and 5 V, without the use of a direction pin. The low ON-state resistance (ron) 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.
