PCA9306DCUR

The PCA9306DCUR is a dual bidirectional I2C bus and SMBus voltage-level translator. It features two channels that allow bidirectional voltage translation between different voltage levels without the need for a direction pin. The PCA9306DCUR is compatible with I2C and SMBus protocols and supports a wide range of operating voltages, from 1.2V to 3.3V for VREF1 and 1.8V to 5.5V for VREF2. This makes it ideal for applications that require communication between devices operating at different voltage levels.

The PCA9306DCUR offers low propagation delay, less than 1.5 nanoseconds, to accommodate standard-mode and fast-mode I2C devices and multiple controllers. It also provides low ON-state resistance between input and output ports, which minimizes signal distortion. The translator switch is controlled by an enable (EN) input, allowing the device to be turned on or off as needed. When the EN input is high, the SCL1 and SDA1 I/O ports are connected to the SCL2 and SDA2 I/O ports, respectively, enabling bidirectional data flow between ports. When the EN input is low, the translator switch is off, and a high-impedance state exists between ports.

The PCA9306DCUR is packaged in a VSSOP8_2X2.3MM package, which is a small, surface-mount form factor that is suitable for use in space-constrained applications. It also features open-drain I2C I/O ports that are 5V tolerant, supporting mixed-mode signal operation. Additionally, the PCA9306DCUR offers ESD protection that exceeds JESD 22 standards, ensuring reliability in harsh environments.

Overall, the PCA9306DCUR is a versatile and reliable voltage-level translator that is suitable for a wide range of applications, including servers, routers, personal computers, and industrial automation systems. Its ability to translate between different voltage levels without the need for a direction pin makes it an excellent choice for designers looking to simplify their I2C and SMBus communication systems.
