What are the key features of LTC4307IMS8-1#PBF?
- Low-offset I2C bus buffer enabling capacitive load isolation and extending I2C bus segment length beyond 400 pF standard limit
- Built-in under-voltage lockout (UVLO) protection preventing spurious bus activity during power-up and power-down transitions
- Compact 8-pin MSOP (S-PDSO-G8) package with 50 mA sink current output suitable for space-constrained designs
What is LTC4307IMS8-1#PBF used for?
The LTC4307IMS8-1#PBF is used in I2C bus extension applications within servers, industrial sensors, and embedded SoC designs where multiple I2C slave devices collectively exceed the 400 pF bus capacitance limit. Acting as a bidirectional buffer, it allows system designers to add additional I2C slaves without degrading signal rise times or violating timing margins. It also protects upstream I2C masters in hot-plug and fault-prone environments encountered in rack-mounted server platforms and industrial field instruments.

Frequently Asked Questions
How does LTC4307IMS8-1#PBF extend I2C bus length beyond the standard 400 pF capacitance limit?
The LTC4307IMS8-1#PBF functions as an I2C bus buffer that isolates the upstream bus segment from the downstream load. By regenerating I2C signals between segments, it allows each segment to independently support up to 400 pF of bus capacitance, effectively doubling or more the total addressable bus length. This is critical in server backplanes and multi-sensor industrial systems with 100 kHz or 400 kHz I2C buses connecting dozens of slave devices.
What protection does the under-voltage lockout in LTC4307IMS8-1#PBF provide during system power sequencing?
The built-in under-voltage lockout (UVLO) keeps the LTC4307IMS8-1#PBF outputs in a high-impedance state when the supply voltage falls below the threshold, typically around 1.7 V to 2.0 V. This prevents corrupted I2C transactions or bus lockups during power-up and power-down sequences, protecting I2C masters and slaves across the 8-pin MSOP-packaged buffer in hot-swap server boards and industrial controllers with staged power rails.
In a multi-board server rack, how many I2C slaves can realistically be managed using LTC4307IMS8-1#PBF buffers?
By inserting one LTC4307IMS8-1#PBF per I2C bus segment, each segment supports up to 400 pF capacitance with a 50 mA sink current output capable of driving 3.3 V or 5 V bus rails. A typical I2C slave device presents 10 pF to 20 pF, so each buffered segment can host 20 to 40 slaves. Using multiple LTC4307 buffers in a tree topology, a server platform can manage hundreds of I2C devices across multiple backplane segments while maintaining 400 kHz fast-mode signaling.
