LTC4307
Low Offset Hot Swappable
2-Wire Bus Buffer with Stuck
Bus Recovery
U FEATURES DESCRIPTIO ■ The LTC®4307 hot swappable, 2-wire bus buffer allows
I/O card insertion into a live backplane without corruption of the data and clock busses. The LTC4307 provides
bidirectional buffering, keeping the backplane and card
capacitances isolated. Low offset and high VOL tolerance
allows multiple devices to be cascaded on the clock and
data busses. If SDAOUT or SCLOUT are low for 30ms, the
LTC4307 will automatically break the bus connection. At
this time the LTC4307 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. ■
