PCA9517AD

The PCA9517AD is a high-speed, bidirectional I²C bus buffer designed to extend the range and increase the number of devices on an I²C bus. It operates between 1.8V and 5.5V and supports standard, fast, and fast-mode Plus I²C data rates up to 1 MHz. The device features two channels, allowing for isolation of the master and slave devices, reducing bus capacitance, and improving signal integrity.
The PCA9517AD maintains I²C compatibility and employs a buffer architecture that provides robust communication even over long distances or with multiple connected devices. It includes built-in pull-up resistors and can automatically detect the I²C bus levels, making it easy to integrate into existing systems.
Applications include data acquisition systems, automotive electronics, and industrial automation, where reliable and flexible communication is essential. The PCA9517AD is particularly valuable in scenarios with multiple devices or where PCB layout constraints hinder direct I²C connections.

The PCA9517AD is a dual bidirectional I2C bus buffer designed to extend the communication range of I2C devices while maintaining signal integrity. Key features include:
1. Dual Channel: Supports two separate I2C channels, allowing multiple devices to be connected.
2. Bidirectional Operation: Facilitates communication in both directions without needing external direction control.
3. Voltage Level Translation: Capable of interfacing devices operating at different voltage levels (1.8V to 5V).
4. Fast Mode Support: Compatible with I2C Fast Mode (up to 400 kHz) and Standard Mode (up to 100 kHz).
5. Low Power Consumption: Designed for energy efficiency, suitable for battery-powered applications.
6. High Speed: Supports bus capacitance up to 400 pF, ensuring robust performance for longer connections.
7. Thermal Protection: Integrated thermal shutdown feature for enhanced reliability.
