What are the key features of LTC4300A-2CMS8#TRPBF?
- Dual-channel I2C hot-swap controller enabling safe live insertion of boards without disrupting active 3.3V or 5V I2C bus traffic
- Bidirectional logic level translation between 3.3V and 5V I2C buses, eliminating the need for external level-shift circuits
- Bus capacitance isolation allows each segment to support extended cable and board trace lengths beyond standard 400 pF I2C limits
What is LTC4300A-2CMS8#TRPBF used for?
The LTC4300A-2CMS8#TRPBF is designed for hot-swappable backplane and PCIe card applications where I2C buses must remain operational during board insertion or removal. It isolates bus capacitance between host and daughter card I2C segments, enabling reliable SMBus and I2C communication at 100 kHz and 400 kHz across mixed 3.3V and 5V systems. Typical uses include server blade management, industrial control card cages, and modular telecommunications equipment.

Frequently Asked Questions
How many I2C channels does the LTC4300A-2CMS8#TRPBF support, and at what bus speeds?
The LTC4300A-2CMS8#TRPBF provides 2 bidirectional I2C channels, supporting standard mode (100 kHz) and fast mode (400 kHz) operation. The bus buffer isolates capacitance between host and card segments, allowing each side to independently support up to 400 pF bus capacitance while maintaining signal integrity.
Which supply voltages are compatible with the LTC4300A-2CMS8#TRPBF for mixed-voltage I2C systems?
The LTC4300A-2CMS8#TRPBF supports bidirectional level translation between 3.3V and 5V I2C logic levels, making it compatible with mixed-voltage system designs. It operates from a single supply as low as 2.7V, enabling interface between legacy 5V systems and modern 3.3V microcontrollers or FPGAs without additional discrete level-shift components.
What makes LTC4300A-2CMS8#TRPBF suitable for hot-swap backplane designs?
The LTC4300A-2CMS8#TRPBF includes active hot-swap circuitry that disconnects the card-side I2C bus during board insertion events, preventing bus contention or data corruption on the host segment. This allows live insertion of plug-in cards in 2-channel I2C topologies without resetting or hanging other devices on the 3.3V or 5V I2C bus.
How compact is the LTC4300A-2CMS8#TRPBF package for space-constrained PCB designs?
The LTC4300A-2CMS8#TRPBF is housed in an 8-pin MSOP package measuring approximately 3.0x3.0 mm, occupying minimal PCB area. This compact footprint makes it suitable for dense server blade and telecom line-card designs where multiple I2C buffer channels must fit within tight space budgets alongside FPGAs and processors.
