LTC4308 Overview
The LTC4308 provides bidirectional buffering, keeping the backplane and card capacitances isolated. Negative offset from output to input allows munication between output bus devices with high VOL and devices on the low voltage input side, where bus supplies can be as low as 0.9V. If SDAOUT or SCLOUT are low for 30ms, the LTC4308 will automatically break the Input-Output connection.
