The LTC4300A-3CDD#PBF from Linear Technology is a sophisticated hot-swappable 2-wire bus buffer that enhances the capabilities of an I²C system by allowing devices or cards to be inserted into or removed from a live backplane without causing glitches and disruptions on the bus lines. This component is designed to improve system reliability and uptime, making it an ideal choice for complex electronic systems that require hot swapping capabilities, such as servers, RAID systems, and telecommunications equipment.

Key Features

• Hot Swappable: Enables devices to be inserted or removed without turning off the system power or causing deleterious effects on the data lines.
• 2-Wire Bus Buffering: Provides buffering for SDA and SCL lines, ensuring signal integrity and robust communication.
• Capacitance Buffering: Allows extension of the I²C bus by buffering the capacitance of the connected devices, supporting more devices or longer trace lengths.
• Prevents Data Corruption: Incorporates rise time accelerators to prevent data corruption during live insertion or removal.
• Stuck Bus Recovery: Features a stuck bus disconnect and recovery function to ensure the bus remains operational even if a device becomes unresponsive.
• Low Standby Current: Minimizes power consumption when the bus is idle, making it suitable for power-sensitive applications.

Applications

• Server Backplanes
• RAID Systems
• Telecommunications Equipment
• Hot Swap Systems
• Network Routers and Switches
