The LTC4303IMS8 TRP8F is a high-performance, hot-swappable 2-wire bus buffer from Linear Technology, designed to enhance system reliability and extend the capabilities of an I2C bus. This integrated circuit allows I/O card insertion into a live backplane without disrupting the data and clock lines. It is an ideal choice for systems that require a robust I2C communication interface with fault-tolerant features.

Key Features

• Hot Swappable: Enables devices to be inserted into or removed from a live backplane without turning off the system, preventing data corruption and ensuring seamless operation.
• Capacitance Buffering: Increases the total system capacitance by buffering the SDA and SCL lines, allowing for more devices or longer trace lengths on the I2C bus.
• Prevents SDA and SCL Corruption: During live insertion, the LTC4303IMS8 TRP8F prevents SDA and SCL corruption through its unique 1-shot trigger mechanism.
• Stuck Bus Recovery: An internal stuck bus recovery timer supports system reliability by deactivating the output buffers if the bus is stuck low for more than 30ms, allowing for a timeout reset.
• Level Translation: The device operates between 2.2V and 5.5V, providing level translation between devices that operate at different logic levels.
• Flow-Through Pinout: Simplifies PCB layout with its convenient flow-through design.

Applications

• Servers and Networking Equipment
• RAID Systems
• Industrial Control
• Telecommunications
