What are the key features of LTC4310IDD-2#TRPBF?
- Hot-swap I2C isolation with active back-driving prevention for safe board insertion without disrupting the bus
- Supports standard (100 kHz), fast (400 kHz), and fast-plus I2C/SMBus speeds with automatic speed detection
- Integrated stuck-bus recovery automatically detects and resolves SCL/SDA lockup conditions
- Operates from 2.7 V to 5.5 V supply with wide temperature range of -40°C to 125°C
What is LTC4310IDD-2#TRPBF used for?
The LTC4310IDD-2#TRPBF is designed for hot-plug server backplanes, data-center blade systems, and industrial control racks where I2C/SMBus segments must be isolated and connected live without glitching the bus. It is also used in redundant power systems, telecom line cards, and medical instrumentation to maintain bus integrity during board insertion or removal.

Frequently Asked Questions
What maximum I2C clock speed does the LTC4310IDD-2#TRPBF support?
The LTC4310IDD-2#TRPBF supports I2C/SMBus communication at up to 400 kHz in fast mode, and also operates in standard 100 kHz mode. Its automatic speed-detection circuitry matches the connected segment speed without manual configuration, making it suitable for mixed-speed bus environments.
How does the LTC4310IDD-2#TRPBF handle stuck-bus conditions on the I2C line?
When the LTC4310IDD-2#TRPBF detects a stuck SCL or SDA line held low for more than approximately 30 ms, its internal stuck-bus recovery engine issues up to 9 clock pulses at 10 kHz to release the stalled slave device. This automatic recovery prevents indefinite bus lockup in systems with fault-prone or intermittently failing I2C peripherals.
Which supply voltage range is supported by the LTC4310IDD-2#TRPBF, and how does that affect system design?
The LTC4310IDD-2#TRPBF operates across a 2.7 V to 5.5 V supply range, allowing direct use in both 3.3 V and 5 V logic systems without level-shift circuitry. This broad range simplifies power-supply design in mixed-voltage server blades, industrial modules, and telecom cards where multiple rail voltages coexist.
In which board-level application scenarios is the LTC4310IDD-2#TRPBF a better fit than a passive I2C buffer?
Unlike a passive I2C buffer, the LTC4310IDD-2#TRPBF provides active isolation that prevents a defective downstream device from pulling the upstream bus low during hot insertion. This makes it the better choice in blade-server backplanes handling 48 V power rails, rack-mounted chassis with up to 16 I2C nodes per segment, and any application where boards must be installed or removed while the system is running.
