Description

The PCA9617ADP is a dual bidirectional I²C-bus buffer with an active-high enable input. It is designed to enhance the performance of I²C and SMBus systems by allowing for longer bus lengths and more devices. The device is particularly useful in applications where signal integrity is challenged by high capacitance loads or long wire runs. The PCA9617ADP provides bidirectional buffering while maintaining the I²C-bus voltage levels, supporting both standard-mode and fast-mode I²C protocols.
Key features include the ability to isolate capacitance on either side of the bus, allowing for a total bus capacitance of up to 400 pF, and supporting voltage translation between 2.5 V to 5.5 V on either side of the device. The active-high enable input allows the buffer to be disabled, effectively isolating the buses. Additionally, the PCA9617ADP ensures glitch-free operation during power-up and power-down sequences, making it suitable for hot swap applications. This makes it ideal for use in complex and extensive I²C networks found in consumer electronics, industrial systems, and computing applications.

Equivalent

The PCA9617ADP is a dual bidirectional I²C-bus buffer. Equivalent products include the TCA9617A from Texas Instruments and the P82B96 from NXP. Additionally, the MAX3372 from Maxim Integrated can also serve as a similar alternative, though it may differ slightly in features or specifications. Always check the datasheet for exact compatibility with your application.

Features

The PCA9617ADP is a dual bidirectional I²C-bus and SMBus buffer designed for bus capacitance buffering and level translation. It features two voltage supply pins, allowing one side to interface with higher voltage levels (up to 5.5V) and the other with lower levels (down to 0.8V), providing level shifting between different voltage domains. Key features include:
1. Dual Bidirectional Buffering: Supports I²C-bus and SMBus, facilitating communication between devices with different voltage levels.
2. Level Translation: Operates between 0.8V to 5.5V, allowing seamless communication between devices with varying supply voltages.
3. High-Speed Operation: Capable of supporting data rates up to 1 MHz, suitable for fast communication protocols.
4. Hot Swap Capability: Includes rise time accelerators to support hot swapping and improve signal integrity.
5. Low Standby Current: Minimizes power consumption in idle states.
6. Stability: Features internal pull-up resistors and bus-hold circuitry for stable operation.
These features make the PCA9617ADP ideal for applications requiring reliable I²C-bus communication across different logic levels and power domains.
