The MAX7328/MAX7329 are 2-wire serial-interfaced
peripherals with eight I/O ports. Any port can be used
as a logic input or an open-drain output.
All input ports are continuously monitored for state
changes (transition detection). Transitions are alerted
through the open-drain, 5.5V-tolerant INT output.
The MAX7328 and MAX7329 versions differ only by their
slave ID address ranges. The MAX7328 has a slave ID
range of 0100xxx (0x20 to 0x27). The MAX7329 has a
slave ID range of 0111xxx (0x38 to 0x3F).
For a similar part with overvoltage-protected I/Os and a
bus RST input that clears the I
the MAX7321 data sheet. The MAX7328/MAX7329 are
members of a family of pin-compatible port expanders
with a choice of input ports, open-drain I/O ports, and
push-pull output ports (see the Selector Guide).
