The TCA9517ADGKR is a robust level-shifting I2C bus repeater from Texas Instruments, designed to ensure signal integrity and extend the communication distance of I2C systems. This integrated circuit is specifically tailored for bidirectional voltage-level translation that is essential for applications requiring I2C signals to be transmitted across different voltage domains.

Key Features

• Dual Bidirectional Voltage Translation: With its dual bidirectional open-drain channel configuration, the TCA9517ADGKR allows for seamless voltage level translation between 1.8V, 2.5V, 3.3V, and 5V power supply domains.
• Enhanced Signal Integrity: This device is equipped with built-in hysteresis which provides improved noise margin and enhances signal integrity, making it an ideal choice for noisy environments.
• Extended I2C Bus Capabilities: By buffering both the data (SDA) and the clock (SCL) lines, the TCA9517ADGKR allows for extending the I2C bus length beyond the typical limits, supporting longer distances between devices.
• Hot-Swap Capability: The TCA9517ADGKR supports hot-swapping, which means devices can be inserted into or removed from a live backplane without shutting down the system.
• Low Standby Current: It is designed to consume a low standby current, making it suitable for battery-powered and power-sensitive applications.
• Robust ESD Protection: The device features 8-kV Human Body Model (HBM) ESD protection on all pins, safeguarding the hardware from electrostatic discharges during handling and operation.

Applications

The TCA9517ADGKR is versatile and can be utilized in a wide range of applications, including but not limited to consumer electronics, mobile devices, servers, networking equipment, and industrial control systems. Its ability to connect low-voltage peripheral modules to higher-voltage main logic boards makes it a go-to solution for multi-voltage systems.
