Working Principles

The PCA9516PW,112 is designed to provide bidirectional voltage-level translation between I2C buses operating at different voltages. It uses a combination of level shifting and buffering techniques to ensure reliable communication between devices.

When an I2C bus master initiates communication, the PCA9516PW,112 automatically detects the direction of the data flow and adjusts the voltage levels accordingly. It provides bidirectional buffering to prevent bus contention and level shifting to match the voltage requirements of the receiving device.

Detailed Application Field Plans

The PCA9516PW,112 can be used in various applications where level shifting and voltage translation are required for I2C communication. Some potential application fields include: - Interfacing between microcontrollers and sensors operating at different voltage levels - Communication between different modules or subsystems within an electronic system - Integration of I2C-based peripherals with different voltage requirements
