What are the key features of LTC4310CDD-2#PBF?
- Supports I2C bus speeds up to 400 kHz (Fast Mode) for compatibility with standard microcontroller I2C peripherals
- Hot-swap I2C card insertion without bus lockup or data corruption in multi-master backplane systems
- Single-channel design in a compact 10-pin no-lead DFN package minimizes board area
- Eliminates stuck-low bus conditions caused by partially inserted or removed I2C daughtercards
- RoHS-compliant (JESD-609 e3) for lead-free, green manufacturing
What is LTC4310CDD-2#PBF used for?
The LTC4310CDD-2#PBF is designed for server backplanes, industrial control racks, and modular instrumentation systems where I2C sensor or peripheral cards must be safely inserted or removed while the system is powered and operating. It prevents the bus lockup conditions that occur when a card's I2C lines are driven to intermediate voltages during hot insertion, protecting all I2C devices sharing the 400 kHz bus. Typical deployment includes management bus controllers in telecom line cards and ATCA/MicroTCA shelf management systems.

Frequently Asked Questions
What maximum I2C bus frequency does the LTC4310CDD-2#PBF support in hot-swap applications?
The LTC4310CDD-2#PBF supports I2C bus frequencies up to 400 kHz, covering both standard mode (100 kHz) and fast mode (400 kHz) I2C specifications. This makes it compatible with the vast majority of commercially available microcontrollers and I2C sensors used in server management, industrial control, and telecom shelf management systems.
How does the LTC4310CDD-2#PBF prevent I2C bus lockup when a card is removed from a live backplane?
When a card is hot-removed, the LTC4310CDD-2#PBF detects the stuck-low condition on SDA or SCL and generates up to 9 clock pulses to release any device holding the bus low, restoring normal I2C bus operation within microseconds. Without this recovery mechanism, a single stuck-low line can freeze all 128 addresses on the bus until the system is power-cycled.
What package does the LTC4310CDD-2#PBF come in, and how many pins does it have?
The LTC4310CDD-2#PBF is housed in a 10-pin no-lead DFN package (JESD-30 code S-PDSO-N10), which occupies a very small PCB footprint of approximately 3 mm × 3 mm. The no-lead construction improves thermal dissipation compared to leaded packages and enables tighter component placement in high-density server and telecom board designs.
In which multi-board system architectures is the LTC4310CDD-2#PBF most beneficial?
The LTC4310CDD-2#PBF provides the greatest benefit in ATCA, MicroTCA, and VME backplane systems, as well as hot-swap server PCI Express add-in cards, where I2C-connected FRU EEPROMs, temperature sensors, and power management ICs must remain accessible at 400 kHz bus speed before, during, and after card insertion or removal events.
