ON Semiconductor PCA9306AMUTCG Dual Bidirectional I2C-Bus and SMBus Voltage-Level Translator

The ON Semiconductor PCA9306AMUTCG is a high-performance, dual bidirectional I2C-bus and SMBus voltage-level translator designed to provide seamless communication between devices operating at different voltage levels. This compact and efficient component is an essential solution for applications that require the interfacing of a low voltage (down to 1.2V) microprocessor to a higher voltage (up to 5.5V) peripheral without the need for a directional control signal.

Featuring a two-bit bidirectional translator for SDA and SCL lines, the PCA9306AMUTCG ensures that data can flow smoothly between high- and low-voltage sides of the device. Its open-drain design, with no direction pin required, simplifies the application circuit and makes it an ideal choice for translating between different logic levels that are found in multi-voltage systems.

The PCA9306AMUTCG supports a wide range of supply voltages, from 1.2V to 3.6V on the A-side (Vref1) and 1.65V to 5.5V on the B-side (Vref2), making it highly versatile for interfacing with today's various digital systems. It is also capable of providing bidirectional voltage translation without the use of a direction pin, which is particularly useful for I2C and SMBus applications.

With its low standby current, the PCA9306AMUTCG is an energy-efficient choice for battery-powered devices. The device also includes an enable (EN) input that can be used to put the device in a low-current standby mode, which is beneficial for power-sensitive applications.

The PCA9306AMUTCG comes in an ultra-small 8-lead UDFN package, which is ideal for space-constrained applications. It is specified for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

Whether you're designing mobile devices, personal electronics, or industrial control systems, the ON Semiconductor PCA9306AMUTCG provides a reliable and straightforward solution for voltage level translation in I2C and SMBus applications.
