LTC4308CMS8 Description

Short technical summary and product information.

The LTC4308CMS8 is a low voltage, level shifting, hot swappable 2-wire bus buffer from Linear Technology (LT). It is optimized for systems operating down to 0.9V and prevents SDA and SCL corruption during live board insertion and removal from backplanes.

 

Key features include a bidirectional buffer with stuck bus recovery, a 30ms stuck bus timeout, and compatibility with non-compliant I2C devices. The device provides ±6kV Human Body Model (HBM) ESD protection, isolating input SDA and SCL lines from output. It operates at data rates up to 400 kHz and supports level translation from 1V to 2.3V/5.5V.

 

This bus buffer is suitable for applications such as live board insertion in servers, capacitance buffering, bus extension, RAID systems, and ATCA. It is available in a compact 8-lead DFN package (3mm x 3mm x 0.75mm).

 

The LTC4308CMS8 is designed to be compatible with I2C, I2C Fast Mode, and SMBus protocols. It features an open-drain output and 1V precharge on SDAOUT and SCLOUT lines, ensuring reliable bus operation.
