Bus Buffer with Enable

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. WhendriventoV_CC, the

ENABLE pin sets normal operation.
