■ The LTC®4303 hot swappable 2-wire Bus Buffer allows I/O
card insertion into a live backplane without corruption of
the data and clock busses. When a connection is made,
the LTC4303 provides bidirectional buffering, keeping the
backplane and card capacitances isolated. If SDAOUT or
SCLOUT is low for ≥ 30ms (typ), the LTC4303 automatically
breaks the data and clock bus connection. At this time the
LTC4303 automatically generates up to 16 clock pulses on
SCLOUT in an attempt to free the bus. A connection will …
