LTC4301L

Hot Swappable 2-Wire

Bus Buffer with Low Voltage

Level Translation

DESCRIPTIO

FEATURES

The LTC^®4301L hot swappable, 2-wire bus buffer allows

I/O card insertion into a live backplane without corruption

of the data and clock busses. In addition, the LTC4301L

SDAIN and SCLIN pins are compatible with systems with

pull-up voltages as low as 1V. Control circuitry prevents

the backplane from being connected to the card until a

stop bit or a bus idle is present. When the connection is

made, the LTC4301L provides bidirectional buffering,

keeping the backplane and card capacitances isolated.

■

Level Translates 1V Signals to Standard 3.3V and

5V Logic Rails

■

Allows Bus Pull-Up Voltages as Low as 1V on

SDAIN and SCLIN

■

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

When driven low, the CS input pin allows the part to

connect after a stop bit or bus idle occurs. Driving CS high

breaks the connection between SCLIN and SCLOUT and

between SDAIN and SDAOUT. A logic high on READY

indicates that the backplane and card sides are connected

together.

■

Supports Clock Stretching, Arbitration and

Synchronization

■

High Impedance SDA, SCL Pins for V_CC= 0V

■

CS Gates Connection from Input to Output

Compatible with I²C^TM, I²C Fast Mode and SMBus

■

Standards (Up to 400kHz Operation)

The LTC4301L is offered in 8-pin DFN (3mm × 3mm) and

MSOP packages.

Small 8-Pin MSOP and DFN (3mm × 3mm) Packages
