Product Overview
The PCA9306 serves as a dual bidirectional voltage translator designed for both the I2C-bus and SMBus. Operating within a voltage range spanning from 1.2V to 5.0V, it eliminates the need for a dedicated direction pin. This board is an excellent choice for efficiently adjusting voltage levels between sensors and your microcontroller.
Allowable Voltage Level Translation
The breakout can translate voltages between 3.3V and 5V.
| VREF1 (i.e. Low Side) | VREF2 (i.e. High Side) |
|---|---|
| 1.2V | 1.8, 2.5V, 3.3V, 5V |
| 1.8V | 2.5V, 3.3V, 5V |
| 2.5V | 3.3V, 5V |
| 3.3V | 5V |
