LTC4306

4-Channel,

2-Wire Bus Multiplexer with

Capacitance Buffering

FEATURES

DESCRIPTIO

The LTC^®4306 is a 4-channel, 2-wire bus multiplexer with

bus buffers to provide capacitive isolation between the

upstream bus and downstream buses. Through software

control,theLTC4306connectstheupstream2-wirebusto

any desired combination of downstream buses. Each

channel can be pulled up to a supply voltage ranging from

2.2V to 5.5V, independent of the LTC4306 supply voltage.

The downstream channels are also provided with

ALERT1-ALERT4 inputs for fault reporting.

■

1:4 2-Wire Multiplexer/Switch

■

Connect SDA and SCL Lines with 2-Wire Bus

Commands

■

Supply Independent Bidirectional Buffer for SDA

and SCL Lines Increases Fan-Out

■

Programmable Disconnect from Stuck Bus

Compatible with I²C and SMBus Standards

■

Rise Time Accelerator Circuitry

■

SMBus Compatible ALERT Response Protocol

■

Two General Purpose Inputs-Outputs

Programmable timeout circuitry disconnects the down-

stream buses if the bus is stuck low. When activated, rise

time accelerators source currents into the 2-wire bus pins

to reduce rise time. Driving the ENABLE pin low restores

all features to their default states. Three address pins

provide 27 distinct addresses.
