Rochester Electronics PCA9617ADP Environmental and export classification status description

The PCA9617ADP is a I2C bus and SMBus bus buffer that allows for multiple masters and slaves to communicate on the same I2C bus. It effectively isolates different sections of an I2C bus and enables system design flexibility while ensuring that signal integrity is maintained over longer distances. The device can be used to extend the reach of the I2C bus and facilitate communication across multiple voltage domains. Functions: - Bus Buffering: Buffers the communication between the I2C master and responder devices. - Isolation: Provides electrical isolation between different segments of an I2C bus. - Voltage Level Shifting: Capable of functioning between different voltage levels, making it suitable for mixed-voltage systems. - Multiple Master Support: Facilitates the connection of multiple masters on the same bus. Applications: - Consumer Electronics: Such as TVs, white goods, and other appliances that utilize I2C communication. - Industrial Automation: For connecting various sensors and controllers that use I2C. - Automotive: Used for connecting various ECUs (Electronic Control Units) to ensure reliable communication. - Computing Devices: For interfacing peripherals such as sensors, displays, and more. Alternative Parts: - PCA9515: Another I2C buffer capable of voltage level shifting and buffer isolation. - PCA9517: Similar functionality but offers a different I2C channel configuration. - PCA9306: A bidirectional level shifter designed for I2C applications that can be an alternative for simpler designs.
