概要

Description

The PCA9517DGKR is a low-voltage, dual bidirectional I2C bus buffer designed to extend the I2C bus capacitance load and increase the distance between devices. It operates within a voltage range of 1.8V to 5.5V, making it suitable for various low-voltage applications. The device supports standard I2C speeds up to 1 MHz and is particularly useful in systems where multiple devices need to communicate over longer distances without signal degradation.
The PCA9517DGKR features two input/output ports that can connect to multiple I2C devices, effectively isolating and buffering the signals to maintain integrity. It incorporates a built-in pull-up resistor structure, significantly simplifying circuit design. The device is housed in a compact 16-pin TSSOP package, providing flexibility for space-constrained applications.
Overall, the PCA9517DGKR enhances I2C system performance by allowing for increased data transmission reliability and flexibility in multi-device configurations.

Features

The PCA9517DGKR is a dual bidirectional I²C bus and SMBus voltage-level translator. Key features include:
1. Voltage Translation: Supports low-voltage I²C bus levels (1.8V to 5V), enabling communication between devices with different power supply voltages.
2. Bidirectional Operation: Allows bidirectional data transfer, facilitating seamless communication between master and slave devices.
3. Integrated Pull-Up Resistors: Contains built-in pull-up resistors for the open-drain outputs, simplifying circuit design.
4. Fast Mode Support: Compatible with I²C Fast-mode (up to 1 MHz) and Fast-mode Plus (up to 1.5 MHz) speeds.
5. Low Power Consumption: Designed for low power operation, making it suitable for battery-powered applications.
6. Compact Package: Available in a 16-pin TSSOP package, providing a space-efficient solution for PCB designs.
These features make the PCA9517DGKR ideal for interfacing components in mixed-voltage environments, enhancing system flexibility and performance.
