DESCRIPTIO  
FEATURES  
■
Bidirectional Buffer* for SDA and SCL Lines  
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.

■
Supports Clock Stretching, Arbitration and  
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-3alsoincorporatesaCMOSthresholdENABLE  
pin which forces the part into a low current mode and iso-  
latesthecardfromthebackplane. WhendriventoVCC, the  
ENABLE pin sets normal operation.
