General Description
The MAX7324 2-wire serial-interfaced peripheral fea-
tures 16 I/O ports that are divided into eight push-pull
outputs and eight inputs. Each input features selectable
internal pullups, overvoltage protection to +6V, and
transition detection with an interrupt output.
All input ports are continuously monitored for state
changes (transition detection). The interrupt is latched,
allowing detection of transient changes. Any combina-
tion of inputs can be selected using the interrupt mask
to assert the INT output. When the MAX7324 is subse-
quently accessed through the serial interface, any
pending interrupt is cleared.
The push-pull outputs are rated to sink 20mA and are
capable of driving LEDs. The RST input clears the serial
interface, terminating any I2C communication to or from
the MAX7324.
The MAX7324 uses two address inputs with four-level
logic to allow 16 I2C slave addresses. The slave
address also enables or disables internal 40kΩ pullups
in groups of four ports.
The MAX7324 is one device in a family of pin-compatible
port expanders with a choice of input ports, open-drain
I/O ports, and push-pull output ports (see Table 1).
The MAX7324 is available in 24-pin QSOP and TQFN
packages, and is specified over the -40°C to +125°C
automotive temperature range.
