The MAX7367/MAX7368/MAX7369 bidirectional, four-
channel I
bus up to four extended buses. The MAX7369 1:4
multiplexer connects the main I
at a time. The MAX7367/MAX7368 four-channel
switches connect the main I
channels at a time.
These devices isolate bus loading by extending the I
bus onto different channels. The MAX7367/MAX7368/
MAX7369 allow more devices to be interconnected to a
master controller and multiple devices with the same
I
are selected through the main I
internal control register of the device.
Any device connected to an I
receive signals. The MAX7367/MAX7368/MAX7369 are
transparent to signals sent and received at each chan-
nel, allowing multiple masters. These devices are com-
patible with the I
synchronization, and arbitration in case multiple mas-
ters address the bus at the same time.
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.
The MAX7367/MAX7369 are available in 20-pin TSSOP
packages, and the MAX7368 is available in a 16-pin
TSSOP package. All devices operate over the -40°C to
+85°C extended temperature range.
