LTC4308 - Low Voltage, Level Shifting Hot Swappable 2-Wire Bus Buffer With Stuck Bus Recovery

The LTC4308 hot swappable, 2-wire bus Buffer allows I/O card insertion into a live Backplane without corruption of the data and Clock busses. The LTC4308 provides bidirectional buffering, keeping the Backplane and card capacitances isolated. Negative offset from output to input allows Communication 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. At this time the LTC4308 automatically generates up to 16 Clock pulses on SCLOUT in an attempt to free the bus. A connection will resume if the stuck bus is cleared. During insertion, the SDAOUT and SCLOUT lines are precharged to 1V to minimize bus disturbances. When driven high, the ENABLE input allows the LTC4308 to connect after a stop bit or bus idle condition. Driving ENABLE low breaks the connection between SDAIN and SDAOUT, SCLIN and SCLOUT. READY is an open-drain output which indicates that the Backplane and card sides are connected.
