1-to-8 I C Bus Switches/Multiplexers with Bus  
Lock-Up Detection, Isolation, and Notification  
6/MAX7358  
General Description  
Features  
The MAX7356/MAX7357/MAX7358 8-channel I2C  
switches/multiplexers expand the main I2C bus to any  
combination of 8 extended I2C buses. They enable a  
master on the main bus to isolate and communicate  
with devices or groups of devices that may otherwise  
have slave address conflicts. Any extended bus can be  
connected or disconnected by control packets from the  
main I2C bus writing to the main control register of  
these I2C switches.  
o Bus Lock-Up Detection and Isolation (MAX7357,  
MAX7358)  
o Host Notification on Detection of Lock-Up  
(MAX7357, MAX7358)  
o Maintain Fault Diagnostic Information (MAX7357,  
MAX7358)  
o Dual-Function RST/INT Provides Lock-Up  
Notification and Hardware Reset (MAX7357,  
MAX7358)  
2
o RST Input Resets I C Interface (MAX7358)  
The MAX7357 and MAX7358 feature an enhanced  
mode that includes a built-in timer used to monitor all  
extended buses for lock-up conditions. If the clock or  
data line of any of these buses is low for more than  
25ms (typ), a lock condition is detected. An optional  
interrupt can be generated through the bidirectional  
RST/INT. The master can read the bus lock-up register  
to find out which extended bus is locked up. The mas-  
ter can also enable the MAX7357 or the MAX7358 to  
send a “flush-out” sequence on the faulty channel.  
There is an optional preconnection check that  
can be enabled to toggle the extended bus clock and  
data line low then high to ensure the downstream bus is  
not locked high prior to connecting it to the host bus.  
o 3 Address Control Inputs  
o Low R  
Switches  
ON  
o Logic-Level Translation  
o Low 0.1µA (typ) Standby Current  
o Support Hot Insertion  
o 100kbps Standard-Mode or 400kbps Fast-Mode  
2
I C Interface  
o Address Translation Allows Multiple Device with  
Same ID  
o 5.5V-Tolerant Inputs  
o 2.3V to 5.5V Supply  
The MAX7356/MAX7357/MAX7358 are transparent  
to signals sent and received at each channel, allowing  
multiple masters. Any device connected to an I2C  
bus can transmit and receive signals; however, only the  
master connected to the host side of the MAX7356/  
MAX7357/MAX7358 should address the device.
