The LTC
4300A-3 hot swappable 2-wire bus buffer allows
I/O card insertion into a live backplane without corruption
of the data and clock busses. When the connection is
made, the LTC4300A-3 provides bidirectional buffering,
keeping the backplane and card capacitances isolated.
Rise-time accelerator circuitry allows the use of weaker
DC pull-up currents while still meeting rise-time require-
ments. During insertion, the SDA and SCL lines are
precharged to 1V to minimize bus disturbances.
The LTC4300A-3 provides level translation between 3.3V
and 5V supplies. The backplane and card can both be
powered with supplies ranging from 2.7V to 5.5V. The
LTC4300A-3 also incorporates a CMOS threshold ENABLE
pin which forces the part into a low current mode and iso-
lates the card from the backplane. When driven to V
CC
, the
ENABLE pin sets normal operation.
The LTC4300A-3 is available in the MSOP and 3mm
