LTC4311IDC#TRMPBF Analog Devices Integrated Circuit (Small Outline No-lead) In Stock
The LTC4311IDC#TRMPBF is an I2C and SMBus rise-time accelerator from Analog Devices that actively drives SDA and SCL lines high to speed up edge transitions on heavily loaded buses. It operates from 2.7 V to 5.5 V and requires no I2C address or configuration, housed in a 6-pin DFN package. Suitable for multi-master I2C buses with large capacitive loads.

What are the key features of LTC4311IDC#TRMPBF?
- Active I2C/SMBus rise-time accelerator for buses loaded up to 400 pF
- Transparent operation — no I2C address or software configuration required
- Wide 2.7 V to 5.5 V supply voltage range covering 3.3 V and 5 V systems
- Supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C modes
- Ultra-compact 6-pin DFN (2 mm × 2 mm) for space-constrained PCB layouts
What is LTC4311IDC#TRMPBF used for?
The LTC4311IDC#TRMPBF is used to restore compliant rise times on I2C or SMBus segments that are overloaded with multiple slave devices, long PCB traces, or cable capacitance exceeding 400 pF. It transparently accelerates SDA and SCL pull-up edges without any address configuration, making it a drop-in fix for buses that fail timing margins at 400 kHz Fast Mode. Server management controllers, industrial sensor networks, and battery management systems with numerous I2C slaves on a single bus regularly deploy this device.

Frequently Asked Questions
What capacitive bus load can the LTC4311IDC#TRMPBF handle while maintaining I2C timing compliance?
The LTC4311IDC#TRMPBF actively drives SCL and SDA high to maintain compliant rise times on I2C buses loaded with up to 400 pF of total capacitance, restoring Fast-Mode 400 kHz timing margins that passive pull-up resistors alone cannot achieve on heavily loaded segments.
Does the LTC4311IDC#TRMPBF require firmware configuration or an I2C address assignment to operate?
No firmware configuration or I2C address is needed; the LTC4311 operates completely transparently on the bus. It monitors SCL and SDA edges and applies active drive assist automatically, making it a drop-in fix that requires only power and ground connections in a 6-pin DFN package.
Which I2C speed modes does the LTC4311IDC#TRMPBF support, and what supply voltage does it require?
The device supports Standard Mode at 100 kHz, Fast Mode at 400 kHz, and Fast-Plus Mode at 1 MHz, operating from a 2.7 V to 5.5 V supply that covers both 3.3 V and 5 V system rails without level-shift components.
