LTC4301

Supply Independent Hot

Swappable 2-Wire Bus Buffer

FEATURES

DESCRIPTIO

TheLTC^®4301supplyindependent,hotswappable,2-wire

bus buffer allows I/O card insertion into a live backplane

without corruption of the data and clock busses. In addi-

tion, the LTC4301 allows the V_CC, SDAIN and SCLIN pull-

up voltage and the SDAOUT and SCLOUT pull-up voltage

to be independent from each other. Control circuitry

prevents the backplane from being connected to the card

until a stop bit or a bus idle is present. When the connec-

tion is made, the LTC4301 provides bidirectional buffer-

ing,keepingthebackplaneandcardcapacitancesisolated.

■

Allows Bus Pull-Up Voltages Above or Below V_CC

■

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 Line from Output

■

10kV Human Body Model ESD Protection

■

1V Precharge On All SDA and SCL Lines

■

Supports Clock Stretching, Arbitration and

Synchronization

■

High Impedance SDA, SCL Pins for V_CC= 0V

During insertion, the SDA and SCL lines are precharged to

1Vtominimizebusdisturbances. Whendrivenlow, theCS

input pin allows the part to connect after a stop bit or bus

idle occurs. Driving CS high breaks the connection be-

tween SCLIN and SCLOUT and between SDAIN and

SDAOUT. The READY output pin indicates that the back-

plane and card sides are connected together.

■

CS Gates Connection from Input to Output

Compatible with I²C^TM, I²C Fast Mode and SMBus

■

Standards (Up to 400kHz Operation)
