The PCA9517ADP,118 is an I2C bus buffer IC (integrated circuit) manufactured by NXP Semiconductors. It is designed to provide level shifting and buffering capabilities for I2C bus signals.
Here are some key features and specifications of the PCA9517ADP,118:
1. I2C Bus Buffer: The PCA9517ADP,118 is specifically designed for buffering and level shifting of I2C bus signals.
2. Bidirectional Level Shifting: It provides bidirectional level shifting between two I2C buses operating at different voltage levels, allowing communication between devices with different voltage requirements.
3. Voltage Translation: The IC translates the logic levels between two voltage domains, ensuring compatibility and proper communication between devices.
4. Multiple Voltage Options: The PCA9517ADP,118 supports voltage translation between 1.2V, 1.8V, 2.5V, 3.3V, and 5V voltage domains.
5. Fast Mode I2C Compatibility: It is compatible with the Fast Mode (400kHz) I2C bus protocol.
6. Two Independent Channels: The IC consists of two independent I2C bus buffer channels, allowing for simultaneous translation and buffering of two separate I2C buses.
7. Package Type: The "ADP" in the part number indicates the package type, which is a 8-lead SOIC (Small Outline Integrated Circuit) package.
The PCA9517ADP,118 is commonly used in various applications where there is a need to interface devices operating at different voltage levels on the I2C bus, such as mixed-voltage systems, communication modules, and sensor networks.
