What are the key features of LTC4313IMS8-3#TRPBF?
- 2-wire I2C/SMBus bus buffer with high-noise-margin inputs enabling reliable communication over long or heavily capacitively loaded bus segments
- Built-in stuck-bus recovery logic automatically releases latched SDA or SCL lines, preventing system lockup without host CPU intervention
- Compact 8-pin MSOP (S-PDSO-G8) package with single 2.7 V to 5.5 V supply rail simplifies integration into space-constrained I2C designs
What is LTC4313IMS8-3#TRPBF used for?
The LTC4313IMS8-3#TRPBF is designed for I2C bus extension and isolation in industrial control panels, server baseboard management, and distributed sensor networks where cable capacitance or multiple device loads degrade signal integrity beyond standard 400 pF bus limits. By buffering both SDA and SCL lines with high-noise margins, it enables reliable multi-segment I2C topologies across 2-wire buses up to standard 400 kHz fast mode. Its automatic bus recovery feature also makes it a reliable safeguard in hot-plug or fault-tolerant systems that must recover without a system reset.

Frequently Asked Questions
How does the LTC4313IMS8-3#TRPBF extend I2C bus capacity beyond the standard 400 pF limit?
The LTC4313IMS8-3#TRPBF buffers both SDA and SCL lines, effectively resetting the capacitive load seen by each upstream bus segment. This allows designers to add additional downstream devices or longer PCB traces while keeping each segment within the standard 400 pF limit, supporting I2C communication at up to 400 kHz fast-mode speed.
What happens if the I2C bus gets stuck and how does the LTC4313IMS8-3#TRPBF handle it?
If SDA or SCL is held low and a stuck condition is detected, the LTC4313IMS8-3#TRPBF automatically generates up to 9 clock pulses on SCL to release any slave device holding the bus low. This stuck-bus recovery operates without CPU firmware intervention, preventing system lockup in multi-master or hot-plug 2-wire environments.
Is the LTC4313IMS8-3#TRPBF appropriate for server baseboard management controllers running on a 3.3 V rail?
Yes. The LTC4313IMS8-3#TRPBF operates from a single supply between 2.7 V and 5.5 V, making it fully compatible with 3.3 V baseboard management controller (BMC) designs. Its 8-pin MSOP footprint occupies minimal board area on dense server management cards, and its I2C buffering capability handles the heavy multi-device bus loading typical in server platforms.
