General Description
The MAX7323 2-wire serial-interfaced peripheral features
eight I/O ports. Four ports are push-pull outputs and the
other four are open-drain I/O ports that are overvoltage
protected up to +6V independent of the supply voltage.
The four I/O ports configured as inputs are continu-
ously monitored for state changes (transition detec-
tion). State changes are indicated by the open-drain
INT output. The interrupt is latched, allowing detection
of transient changes. When the MAX7323 is subse-
quently accessed through the serial interface, any
pending interrupt is cleared.
The four push-pull and four open-drain 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 MAX7323.
The MAX7323 uses two address inputs with four-level
logic to allow 16 I2C slave addresses. The slave
address also determines the power-up logic state for
the I/O ports, and enables or disables internal 40k
Ω
pullups for the input ports in groups of two ports.
The MAX7323 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 MAX7323 is available in 16-pin QSOP and 16-pin
TQFN packages, and is specified over the automotive
temperature range (-40°C to +125°C).
