Overview
Description
The PCA9306DCUR is a dual bidirectional I2C voltage-level translator designed to enable communication between two devices or systems operating at different voltage levels. It is commonly used in applications where there's a need to interface between I2C or SMBus devices with different supply voltages. The device supports voltage translation between 1.0 V to 5.5 V on the low-voltage side and 1.8 V to 5.5 V on the high-voltage side.
Key features include its ability to operate at speeds up to 400 kHz, and it requires no direction pin, simplifying design and reducing pin count. The PCA9306DCUR is typically housed in a small package, such as the VSSOP-8 (very small shrink outline package), making it suitable for space-constrained applications. It is often used in consumer electronics, computing, and industrial applications to ensure reliable data transfer across varied voltage domains.
Overall, the PCA9306DCUR offers an efficient solution for level shifting in I2C applications, ensuring compatibility and stability across different electronic components.

Pinout
The PCA9306DCUR is a dual bidirectional I2C voltage-level translator produced by Texas Instruments. This device is commonly used for level shifting in I2C and SMBus applications, accommodating the voltage differences between two logic levels.
The PCA9306DCUR comes in an 8-pin package. The key pins and their functions are as follows:
1. VREF1: Reference voltage for the low-voltage side.
2. VREF2: Reference voltage for the high-voltage side.
3. EN (Enable): This pin enables the device when driven high.
4. SCL1: Low-voltage side I2C clock input/output.
5. SCL2: High-voltage side I2C clock input/output.
6. SDA1: Low-voltage side I2C data input/output.
