PCA9306D Dual Bi-Directional I2C Bus and SMBus Voltage Level Translator SOIC-8
The PCA9306 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0V to 3.6V (Vref) and 1.8V to 5.5V (Vbias(ref)).
The PCA9306 allows bidirectional voltage translations between 1.0V and 5V 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.
