I C Port Expander with  
4 Push-Pull Outputs and 4 Inputs  
General Description  
Features  
400kHz I2C Serial Interface  
+1.71V to +5.5V Operation Voltage  
The MAX7322 2-wire serial-interfaced peripheral features  
four push-pull outputs and four input ports with selectable  
internal pullups. Input ports are overvoltage protected to  
+6V and feature transition detection with interrupt output.  
The four input ports are continuously monitored for state  
changes (transition detection). The interrupt is latched,  
allowing detection of transient changes. Any combination  
of inputs can be selected using the interrupt mask to  
assert the open-drain INT output. When the MAX7322 is  
subsequently accessed through the serial interface, any  
pending interrupt is cleared.  
4 Push-Pull Output Ports Rated at 20mA Sink  
Current  
4 Input Ports with Maskable, Latching Transition  
Detection  
Input Ports are Overvoltage Protected to +6V  
Transient Changes are Latched, Allowing  
Detection Between Read Operations  
INT Output Alerts Change on Any Selection of  
Inputs  
The four push-pull outputs are rated to sink 20mA, and  
are capable of driving LEDs.  
AD0 and AD2 Inputs Select from 16 Slave  
Addresses  
The RST input clears the serial interface, terminating any  
Low 0.6µA (typ) Standby Current  
-40°C to +125°C Operating Temperature Range  
I2C communication to or from the MAX7322.  
The MAX7322 uses two address inputs with four-level  
logic to allow 16 I2C slave addresses. The slave address  
also sets the power-up default logic state for the four out-  
put ports, and enables or disables internal 40kΩ pullups  
for the input ports.  
The MAX7322 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 MAX7322 is available in 16-pin QSOP and TQFN  
packages, and is specified over the -40°C to +125°C  
automotive temperature range.
