The LTC4307IDD-1#PBF is a hot-swappable 2-wire bus buffer from Linear Technology that provides seamless I2C bus isolation while maintaining full system operation. Designed for applications requiring a robust I2C interface, it is particularly suitable for advanced systems where a large number of devices are connected, or where isolation between different bus segments is required.

Key Features

• Hot-Swappable: Allows devices to be added or removed from a live I2C bus without causing glitches or disruptions, ensuring continuous communication.
• Level Translation: The LTC4307IDD-1#PBF can translate between different logic levels ranging from 1.5V to 5.5V, enabling it to interface with various I2C devices.
• Stuck Bus Recovery: An integrated stuck bus recovery feature helps to clear up data congestion by resetting the bus if a device becomes unresponsive.
• Prevents Back-Driving: The buffer's strong pull-up current source on the input prevents back-driving and maintains the integrity of the data lines.
• Capacitance Buffering: It reduces system capacitance by isolating the bus capacitance of the backplane or expansion cards from the main bus.

Applications

• Server and Storage Systems
• Industrial Control Systems
• Advanced Modular Systems
• Hot-Swappable Cards
• Networking Equipment

Product Specifications

The LTC4307IDD-1#PBF comes in a small 8-lead DFN package with a temperature range of -40°C to +85°C. Its fail-safe feature ensures that the bus lines are not left floating if the device is powered down, thereby maintaining system stability. The package is RoHS compliant, adhering to environmental standards for hazardous substances.
