I C Port Expander with 4 Push-Pull Outputs  
and 4 Open-Drain I/Os  
General Description  
Features  
The MAX7323 2-wire serial-interfaced peripheral fea-  
tures eight I/O ports. Four ports are push-pull outputs  
and the other four are open-drain I/O ports, indepen-  
dent of supply voltage.  
400kHz I2C Serial Interface  
+1.71V to +5.5V Operating Voltage  
4 Push-Pull Output Ports Rated at 20mA Sink  
Current  
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.  
4 Open-Drain I/O Ports Rated to 20mA Sink Current  
4 I/O Ports Are Overvoltage Protected to +6V  
Transient Changes Are Latched, Allowing Detection  
Between Read Operations  
INT Output Alerts Change on Inputs  
AD0 and AD2 Inputs Select from 16 Slave  
The four push-pull and four open-drain outputs are  
rated to sink 20mA and are capable of driving LEDs.  
Addresses  
Low 0.6µA (typ) Standby Current  
The RST input clears the serial interface, terminating  
any I C communication to or from the MAX7323.

-40°C to +125°C Operating Temperature Range  
The MAX7323 uses two address inputs with four-level  
2
logic to allow 16 I C slave addresses. The slave  
Ordering Information  
address also determines the power-up logic state for  
the I/O ports, and enables or disables internal 40kΩ  
pullups for the input ports in groups of two ports.
