What are the key features of LTC4307IMS8-1#TRPBF?
- Bidirectional I2C buffer isolates capacitive loads up to 400 pF per segment
- Supports 100 kHz Standard and 400 kHz Fast-mode I2C operation
- Wide 2.7 V to 5.5 V supply voltage range
- Under-voltage lockout protects the bus during power-up and power-down sequences
- 50 mA peak output current sink for robust bus drive
- MSOP-8 package enabling compact signal-chain layouts
What is LTC4307IMS8-1#TRPBF used for?
LTC4307IMS8-1#TRPBF is used in multi-master I2C networks where long PCB traces or numerous peripherals increase bus capacitance beyond the 400 pF limit. It is ideal for server backplane management buses, industrial sensor arrays, and hot-swap card architectures that require bus isolation during board insertion. The integrated under-voltage lockout prevents bus corruption during system power cycling.

Frequently Asked Questions
How much capacitance can the LTC4307IMS8-1#TRPBF handle per I2C segment, and why does that matter for multi-node sensor networks?
The LTC4307IMS8-1#TRPBF can buffer I2C segments with up to 400 pF of bus capacitance per side, effectively doubling the number of nodes or trace length allowed by the I2C specification. In a sensor network with 10 or more devices, unbuffered buses quickly exceed the 400 pF limit, causing signal degradation at 400 kHz Fast-mode speeds; inserting this buffer restores clean rise times.
What supply voltage range is supported, and can this device operate in a 3.3 V system alongside 5 V legacy I2C devices?
The device operates from 2.7 V to 5.5 V, allowing it to sit between a 3.3 V microcontroller I2C bus and a 5 V legacy peripheral bus. Each side can be powered from a different supply within that range, enabling safe level translation while the under-voltage lockout at approximately 2.7 V prevents false bus transactions during power sequencing.
When replacing an LTC4306 with LTC4307IMS8-1#TRPBF in a board redesign, what functional differences should an engineer account for?
The LTC4307 provides a single bidirectional buffer channel in an MSOP-8 package, whereas the LTC4306 is a 4-channel device. If the design requires only 1 isolation point, the LTC4307 reduces BOM cost and board area to roughly 3 mm × 3 mm. The 50 mA peak sink current and 400 kHz maximum I2C speed are identical, so no firmware changes are needed.
