General Description
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.
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.
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.
The MAX7356/MAX7357/MAX7358 are available in 24-pin
TSSOP and TQFN packages and are specified over the
extended -40°C to +85°C temperature range.
