Applications
The LTC4307IMS8#TRPBF is designed for high-availability systems that require live insertion and removal of daughter cards or modules on a shared I2C or SMBus backplane. Its bus buffer architecture prevents SDA/SCL bus lockup during hot-swap events and allows longer PCB traces by driving up to 400 pF capacitive loads on each channel. Telecom line cards, server management boards, and industrial controller backplanes commonly employ this device for reliable multi-master bus management.

Frequently Asked Questions
What capacitive load can the LTC4307IMS8#TRPBF drive on its I2C bus outputs?
The LTC4307IMS8#TRPBF buffers each bus segment and can drive up to 400 pF of capacitive load per channel, allowing designers to extend I2C or SMBus traces considerably longer than unbuffered implementations support.
Over what supply voltage range does the LTC4307IMS8#TRPBF operate, and does it support mixed-voltage systems?
The device operates from a 2.7 V to 5.5 V supply range and supports bidirectional voltage-level translation between its two bus sides, making it suitable for mixed 3.3 V and 5 V I2C backplane designs.
When is a bus buffer like the LTC4307IMS8#TRPBF necessary instead of a standard I2C repeater?
A hot-swap bus buffer is required when boards must be inserted or removed while the backplane remains powered; the LTC4307 prevents SDA/SCL lockup during those events, protecting all 8-pin MSOP connected devices from bus hangs that a simple repeater would not prevent.
