LTC4308CMS8#PBF - Hot Swappable 2-Wire Bus Buffer

The LTC4308CMS8#PBF is a sophisticated integrated circuit from Linear Technology designed for seamless, hot-swappable insertion into a live I2C bus without causing glitches or disruptions. This hot-swappable 2-wire bus buffer allows a card to be inserted into or removed from a live backplane without corrupting the data on the bus. It is particularly useful in complex systems where modules need to be exchanged or upgraded without powering down the system.

Key Features

• Hot Swap Capability: Enables the device to be inserted into or removed from a live system without switching off the power or resetting the bus.
• 2-Wire Bus Buffer: Ensures strong buffering to maintain signal integrity, allowing for extended cable lengths and robust noise immunity.
• No Glitch Operation: The device is designed to prevent data corruption during live insertion and removal.
• MS8 Package: The LTC4308 is offered in an MS8 package, which is a small, surface-mountable option ideal for space-constrained applications.
• Capacitance Buffering: Allows a card to present only a fixed capacitive load to the backplane, regardless of the number of devices on the card.
• Automatic Recovery: The built-in rise time accelerator circuitry ensures quick recovery from stuck bus conditions.

Applications

The LTC4308CMS8#PBF is versatile and can be used in a variety of applications where I2C or SMBus devices are present, such as:

• Servers and RAID systems
• Telecommunications equipment
• AdvancedTCA systems
• Network routers and switches
• Industrial control systems

Its robust design and performance make it an excellent choice for any application requiring a durable and reliable I2C bus buffer solution. With its hot-swap capability and glitch-free operation, the LTC4308CMS8#PBF ensures minimal downtime and maximum system availability.
