4-Channel I C Switches/Multiplexer  
8/MAX7369  
General Description  
Features  
o Four-Channel, Bidirectional Bus Expansion  
o Voltage-Level Translation  
The MAX7367/MAX7368/MAX7369 bidirectional, four-  
2
2
channel I C switches/multiplexer expand the main I C  
bus up to four extended buses. The MAX7369 1:4  
o Low 6µA (typ) Supply Current, 0.1µA (typ)  
2
multiplexer connects the main I C bus to one channel  
Standby Current  
at a time. The MAX7367/MAX7368 four-channel  
o Low 16Ω (typ) On-Resistance  
2
switches connect the main I C bus to one or more  
2
o Channel Selection Through I C  
channels at a time.  
2
o I C-Compatible Normal or Fast Mode  
2
These devices isolate bus loading by extending the I C  
o Device Address Selection  
bus onto different channels. The MAX7367/MAX7368/  
MAX7369 allow more devices to be interconnected to a  
master controller and multiple devices with the same  
Up to Four Addresses (MAX7367)  
Up to Eight Addresses (MAX7368/MAX7369)  
o Bus-Loading Isolation  
2
I C address to communicate to a master. The channels  
2
are selected through the main I C bus by writing to the  
o Support Clock Stretch, Synchronization, and  
Arbitration  
internal control register of the device.  
o Hot Insertion  
2
Any device connected to an I C bus can transmit and  
receive signals. The MAX7367/MAX7368/MAX7369 are  
transparent to signals sent and received at each chan-  
nel, allowing multiple masters. These devices are com-  
o 2.3V to 5.5V Supply Voltage Range  
o 5V-Tolerant Inputs  
o Interrupt from Extended Buses  
2
patible with the I C protocol of clock stretch,  
(MAX7367/MAX7369)  
synchronization, and arbitration in case multiple mas-  
ters address the bus at the same time.  
o Hardware Reset (MAX7367/MAX7368)  
All devices are set to the default state during initial  
power-up. The MAX7367/MAX7368 have a RESET input  
allowing external circuitry to set the MAX7367/MAX7368  
to its default state anytime after the device has pow-  
ered up. The MAX7367/MAX7369 have interrupt inputs,  
allowing devices on the extended bus to send an inter-  
rupt signal to the master on the main bus.
