MAX7367/MAX7368/MAX7369
4-Channel I2C Switches/Multiplexer

Channel Selection
Each channel selected contains an SD_ and SC_ pair.
Select a channel by writing a control byte after a success-
ful acknowledge of the slave address. The last 4 bits of the
control byte determine which channel(s) is selected for the
MAX7367/MAX7368 as shown in Table 1. The last 3 bits of
the control byte determine which channel is selected for
the MAX7369 as shown in Table 2. The selected channels
are activated after the stop condition. When a channel is
selected, the respective SD_/SC_ pair is logic-high, ensur-
ing no false conditions occur on the bus.
Interrupt Logic (MAX7367/MAX7369)
The MAX7367/MAX7369 have four interrupt inputs, one for
each channel, and one
INT output. The INT output is an
open-drain output that requires a pullup resistor. The
INT
output is asserted by a low-logic signal on any of the
INT_
inputs, and it is deasserted only when all the
INT_ inputs
are logic-high. Bits 4–7 of the MAX7367/MAX7369
control/interrupt register store the state of the
INT_ for
each channel as shown in Table 3 and Figures 6 and 8.
The logic level of
INT_ is not latched. Drive the respective
INT_ input high to remove the interrupt condition for the
channel. An interrupt can occur on any channel, regard-
less of whether it is selected or not selected.
After a device generates an interrupt on one of the
channels, the interrupt input is loaded into the
control/interrupt register when a read is performed. To
determine which device is generating the interrupt,
read the contents of the control/interrupt register to
determine which channel is issuing the interrupt, then
write the appropriate command to the control/interrupt
register to select the interrupted channel. Read from all
devices on the interrupted channel to determine the
exact source of the interrupt.
