Product details

What this I²C accelerator does on the bus

Supply current is 200µA typical, low enough that a battery-powered sensor node or portable instrument won't see a meaningful hit to its quiescent budget. The SC-70-6 package (also called SOT-363) takes minimal board area — useful when you're retrofitting an existing layout that has margin trouble on the I²C bus.

Temperature grade and where it fits

Rated for 0°C to 70°C commercial operation. That covers office equipment, consumer electronics, lab instruments, and indoor telecom gear. Not the part for an engine bay, outdoor base station, or cold-chain sensor pod — those need the industrial-temperature LTC4311ISC6#TRPBF variant, which extends to -40°C to 85°C.

Sourcing this part — what to expect

ROHS3 compliance means the part meets current environmental restrictions for lead and other hazardous substances, simplifying compliance for products sold into regulated markets.

Frequently asked questions

Can LTC4311CSC6#TRMPBF work with a 1.8V supply?

Yes. The supply range is 1.6V to 5.5V, so 1.8V logic buses are within spec. The part will accelerate rise times on a 1.8V I²C bus without needing a separate regulator.

Is LTC4311CSC6#TRMPBF compatible with 5V I²C buses?

Yes. The 1.6V to 5.5V supply range covers 5V logic. The part's output is 2-wire bus, same as its input, so it passes 5V-level signals correctly.

What is the LTC4311CSC6#TRMPBF used for?

It is an I²C bus accelerator that sharpens rising edges on SDA and SCL lines, allowing the bus to drive higher capacitive loads — longer PCB traces, more slave devices, or connectors — while maintaining 400kHz data rate.

When sourcing LTC4311CSC6#TRMPBF, what is the closest functional alternate?

The LTC4311CDC#TRMPBF is the same accelerator in a different package (SC-70-6 vs DFN). Same 400kHz data rate, same 1.6V supply minimum, same single-channel I²C acceleration. The LTC4311ISC6#TRPBF is the industrial-temperature (-40°C to 85°C) version in the same SC-70-6 package.
