PCA9517DR

The PCA9517DR is a bidirectional I2C bus repeater developed by NXP Semiconductors. It is designed to enable communication between two I2C bus segments with different voltage levels, supporting level shifting between 1.0 V to 5.5 V on the A-side and 2.3 V to 5.5 V on the B-side. This capability allows devices operating at different voltages to be connected without compatibility issues.
Key features of the PCA9517DR include its ability to buffer I2C signals, allowing for longer bus lengths and more devices on the bus, and its high-speed operation that supports data rates up to 1 MHz. It also features automatic bus direction control, which simplifies design by eliminating the need for additional control signals.
The device is typically used in applications requiring I2C communication across different voltage domains, such as in consumer electronics, automotive systems, and industrial equipment. It comes in a compact, space-saving package suitable for surface-mount assembly. The PCA9517DR enhances both signal integrity and reliability in I2C communication networks.

The PCA9517DR is an I2C-bus repeater from NXP. Some equivalent products include the TCA9517 from Texas Instruments, which serves a similar purpose as a level-shifting I2C bus repeater. Other potential alternatives are the ON Semiconductor's LCX1004 and Microchip's MCP23017, although they may differ slightly in features or specifications. Always compare datasheets for compatibility in specific applications.

The PCA9517DR is a level-translating I2C bus repeater manufactured by Texas Instruments. It features dual bidirectional data transfer paths for SDA and SCL lines, facilitating communication between I2C devices operating at different voltage levels. The device supports voltage translation between 0.9 V and 5.5 V, making it suitable for interfacing a variety of low and high-voltage components. It operates at speeds up to 1 MHz in Fast-mode Plus (Fm+) and can handle capacitive buses up to 400 pF, effectively supporting longer buses and more devices.
The PCA9517DR includes a logic level translation capability and features hot swapping, which allows for the dynamic addition and removal of devices on the I2C bus without rebooting the system. It also ensures glitch-free operation and is equipped with a power-up/down high-impedance I2C pins, which prevent bus corruption during power cycles. The device is housed in a small, space-saving package, making it ideal for modern, compact electronics.

The PCA9517DR is an I²C-bus repeater with a 10-pin configuration, housed in an SOIC (Small Outline Integrated Circuit) package. This device functions to enable I²C communication over extended distances by buffering data lines, providing level shifting, and isolating capacitance.
Key pin functions include:
- VCCA (Pin 1): Supply voltage for the side A I²C-bus.
