What are the key features of LTC4313IMS8-3#PBF?
- 2-wire I2C/SMBus bus buffer supporting up to 400 kHz fast-mode with high noise margin for reliable long-line communication
- Capacitive load isolation allows connection of boards with up to 400 pF bus capacitance without degrading signal integrity
- Hot-swap compatible design enables live card insertion on active I2C/SMBus backplanes without bus lockup or data corruption
What is LTC4313IMS8-3#PBF used for?
The LTC4313IMS8-3#PBF is used in server backplane and blade server designs where multiple I2C/SMBus devices must be connected over long PCB traces or connectors with high capacitive loading up to 400 pF per segment. It is well suited for telecom and industrial systems requiring hot-swap card insertion without disturbing the live 400 kHz bus. The device also supports multi-card chassis designs where bus isolation between slots prevents a single faulty card from locking the shared I2C bus.

Frequently Asked Questions
What I2C bus speeds does the LTC4313IMS8-3#PBF support and how much capacitive load can it drive per segment?
The LTC4313IMS8-3#PBF supports standard-mode (100 kHz) and fast-mode (400 kHz) I2C and SMBus communication. It can drive bus segments with up to 400 pF capacitance on each side of the buffer, significantly extending the effective reach of a 2-wire bus in backplane and multi-drop server rack designs compared to a direct connection.
How does the LTC4313IMS8-3#PBF enable safe hot-swap card insertion on a live I2C backplane?
The LTC4313IMS8-3#PBF includes hot-swap circuitry that pre-charges the downstream bus to the upstream bus voltage before completing the connection. This prevents the capacitive glitch that would otherwise occur at 400 kHz when a card with 400 pF of bus capacitance suddenly loads the live I2C lines, avoiding bus lockup or spurious START conditions that corrupt in-progress transactions.
When would the LTC4313IMS8-3#PBF be chosen over a simple I2C multiplexer such as the TCA9548A in a server design?
The LTC4313IMS8-3#PBF is preferred over a multiplexer when the design requires true bidirectional bus buffering with hot-swap support rather than segment switching. Where a TCA9548A switches between 8 channels with 400 kHz capability, the LTC4313IMS8-3#PBF provides a single isolated buffer that allows one segment to present up to 400 pF to the upstream bus without corrupting live hot-swap events across multiple slots.
What is the package of the LTC4313IMS8-3#PBF and how does it fit a compact board layout?
The LTC4313IMS8-3#PBF comes in an 8-pin MSOP (TSOP-8 / S-PDSO-G8) package with a shrink pitch, occupying a very small PCB footprint suitable for dense server and industrial control boards. Its 8-pin outline allows placement close to the backplane connector, minimizing the stub length on the buffered I2C segment and reducing parasitic capacitance below the 400 pF per-segment limit.
