Hot Swappable

2-Wire Bus Buffers

DESCRIPTIO

FEATURES

■

Bidirectional Buffer for SDA and SCL Lines

The LTC^®4300A series hot swappable 2-wire bus buffers

allow I/O card insertion into a live backplane without

corruption of the data and clock busses. When the con-

nection is made, the LTC4300A-1/LTC4300A-2 provide

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 requirements. During insertion, the

SDA and SCL lines are precharged to 1V to minimize bus

disturbances.

■

READY Open Drain Output (LTC4300A-1)

■

1V Precharge on all SDA and SCL Lines

The LTC4300A-1 incorporates a CMOS threshold digital

ENABLE input pin, which forces the part into a low current

modewhendriventogroundandsetsnormaloperationwhen

driven to V_CC. It also includes an open drain READY output

pin, which indicates that the backplane and card sides are

connectedtogether. TheLTC4300A-2replacestheENABLE

pin with a dedicated supply voltage pin, V_CC2, for the card

side, providinglevelshiftingbetween3.3Vand5Vsystems.

Both the backplane and card may be powered with supply

voltages ranging from 2.7V to 5.5V, with no contraints on

which supply voltage is higher. The LTC4300A-2 also re-

places the READY pin with a digital CMOS input pin, ACC,
