LTC4300A-1/LTC4300A-2

Hot Swappable

2-Wire Bus Buffers

FEATURES

DESCRIPTION

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

allowI/Ocardinsertionintoalivebackplanewithoutcorrup-

tion of the data and clock busses. When the connection is

made,theLTC4300A-1/LTC4300A-2providebidirectional

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.

Bidirectional Buffer for SDA and SCL Lines

Increases Fanout

Prevents SDA and SCL Corruption During Live

Board Insertion and Removal from Backplane

Isolates Input SDA and SCL Lines from Output

Compatible with I C, I C Fast Mode and SMBus

Standards (Up to 400kHz Operation)

Low I Chip Disable: <1μA (LTC4300A-1)

READY Open Drain Output (LTC4300A-1)

1V Precharge on all SDA and SCL Lines

Supports Clock Stretching, Arbitration and

Synchronization

The LTC4300A-1 incorporates a CMOS threshold digital

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

mode when driven to ground and sets normal operation

5V to 3.3V Level Translation (LTC4300A-2)

when driven to V . It also includes an open drain READY

sides are connected together. The LTC4300A-2 replaces

the ENABLE pin with a dedicated supply voltage pin, V

APPLICATIONS

for the card side, providing level shifting between 3.3V

and 5V systems. Both the backplane and card may be

powered with supply voltages ranging from 2.7V to 5.5V,

with no constraints on which supply voltage is higher. The

LTC4300A-2 also replaces the READY pin with a digital

CMOS input pin, ACC, which enables and disables the

rise-time accelerator currents.
