LTC4309 Level Shifting Low Offset Hot Swappable 2-Wire Bus Buffer

The LTC®4309 hot swappable 2-wire bus buffer allows I/O card insertion into a live backplane without corruption of the data and clock busses. The LTC4309 provides bidirectional buffering, keeping the backplane and card capacitances isolated. Low offset and high VOL tolerance allows cascading of mult.

LTC4309 Features

* Bidirectional Buffer Increases Fanout n 60mV Buffer Offset Independent of Load n Optional Disconnect when Bus is Stuck Low n Prevents SDA and SCL Corruption During Live Board Insertion and Removal from Backplane n Level Shift 2.5V, 3.3V and 5V Busses 2 n Compatible with Non-Compliant V OL I C Device
