The LTC4307CMS8-1#PBF is a robust I²C bus buffer and extender from Linear Technology, designed to provide stable data transmission in complex or noisy environments. This device is essential for applications that require extending the I²C bus over long distances or connecting multiple devices that may otherwise cause signal integrity issues.

Key Features

• Hot-Swappable: The LTC4307 allows devices to be inserted or removed from a live I²C bus without corrupting the data stream or causing system crashes.
• Level Translation: It supports level translation between 1.5V, 2.5V, 3.3V, or 5V buses, enabling communication between devices operating at different voltage levels.
• Stuck Bus Recovery: An internal watchdog timer automatically disengages the input from the output if the SDA or SCL lines are stuck low, preventing system lock-up.
• Prevents Back-Driving: The LTC4307 includes strong pull-up currents to VCC and pull-down currents to GND, which prevent back-driving of the upstream bus when the downstream bus is driven low.
• Flow-Through Pinout: The flow-through design minimizes the PCB layout complexity and eases the routing of I²C signals.
• Capacitance Buffering: It can buffer heavily capacitive loads, thus allowing a significant increase in total bus capacitance and the number of connected devices.
