Key Features
- Hot-swappable 2-wire bus buffer supporting up to 400 kHz Fast-Mode I2C
- Bus voltage range 2.7 V to 5.5 V for flexible supply compatibility
- Stuck-bus recovery circuit prevents bus lockup
- Isolates upstream bus from downstream faults for improved system reliability
- Low 45 Ω on-resistance buffers with bidirectional signal support
Applications
The LTC4307IMS8#PBF is well-suited for server backplanes and blade server architectures that require hot-swappable I2C bus expansion with fault isolation. It is also used in industrial sensor networks and telecom line cards where multiple I2C devices must share a bus without causing lockup. Medical instrumentation and data acquisition systems benefit from its stuck-bus recovery and robust 2.7 V to 5.5 V operating range.

Frequently Asked Questions
How fast can the LTC4307IMS8#PBF operate on an I2C bus, and what voltage levels does it support?
The LTC4307IMS8#PBF supports standard-mode 100 kHz and fast-mode 400 kHz I2C operation. Its bus voltage range spans 2.7 V to 5.5 V, making it compatible with both 3.3 V and 5 V logic systems. This flexibility is essential for mixed-voltage server backplane and telecom designs.
Which server or industrial designs benefit most from this IC's hot-swap and stuck-bus recovery features?
Server backplanes with hot-pluggable modules benefit greatly because the LTC4307IMS8#PBF isolates the upstream I2C bus from downstream faults during card insertion. Its stuck-bus recovery circuit automatically releases a locked 2-wire bus within approximately 35 ms, reducing system downtime in industrial sensor networks and telecom equipment with up to 24 downstream I2C slaves.
How does the MSOP-8 package size of the LTC4307IMS8#PBF compare to larger alternatives for compact PCB layouts?
The MSOP-8 package measures approximately 3 mm × 3 mm, making it one of the smallest footprints for a 2-wire bus buffer with hot-swap capability. This 8-pin form factor saves significant board space compared to SOIC-8 alternatives, which typically occupy about 5 mm × 4 mm, enabling denser PCB layouts in space-constrained server blades and portable instruments.
