Description and Introduction

Level-Translating I2C Bus Repeater 8-VSSOP -40 to 85 The **PCA9517DGKR** from Texas Instruments is a high-performance, dual bidirectional I²C bus and SMBus voltage-level translator designed to facilitate seamless communication between devices operating at different voltage levels. This compact and efficient component is particularly useful in mixed-voltage systems, ensuring reliable data transfer while preventing bus contention and signal corruption.  

Featuring two independent bidirectional channels, the PCA9517DGKR supports voltage translation between 2.3V and 5.5V, making it ideal for applications such as industrial automation, consumer electronics, and embedded systems. Its built-in buffering capability enhances signal integrity, reducing the risk of data errors in noisy environments.  

The device incorporates a low standby current, optimizing power efficiency in battery-operated systems. Additionally, its hot-swappable design allows for safe insertion and removal without disrupting the bus, improving system flexibility.  

Housed in a small **8-pin VSSOP package**, the PCA9517DGKR offers a space-saving solution for PCB designs where board real estate is limited. With robust ESD protection and compatibility with I²C and SMBus standards, this translator ensures reliable performance in demanding applications.  

Engineers seeking a dependable voltage-level translator for I²C-based systems will find the PCA9517DGKR a practical and efficient choice.

Application Scenarios & Design Considerations

Level-Translating I2C Bus Repeater 8-VSSOP -40 to 85

Alternative Part Number

  • TCA9517DGKR --: Pin-compatible I2C level translator from TI's TCA series with similar voltage translation function and same package.
  • PCA9515ADGKR --: I2C bus repeater/level translator in the same VSSOP package, suitable for similar bus buffering applications.
  • TCA9406DCTR --: Dual bidirectional I2C level translator offering comparable voltage translation capability in a small package.
  • TCA9517DGKR --: TI's own level-translating I2C bus repeater in the same VSSOP-8 package with equivalent function and pinout, making it a near drop-in replacement.
  • PCA9515ADGKR --: Similar I2C bus repeater from the PCA9515 family in the same package; usable when only basic buffering is needed, though it lacks the full level-translation feature.
  • LTC4311IMS8 --: I2C bus accelerator/buffer in MSOP-8 that improves bus drive and capacitance handling; a functional alternative when level translation is not strictly required.
