I C Port Expander with Eight Push-Pull Outputs  
and Eight Inputs  
General Description  
Features  
400kHz, +6V-Tolerant I2C Serial Interface  
+1.71V to 5.5V Operating Voltage  
Eight Push-Pull Outputs  
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.  
Eight Input Ports with Maskable, Latching  
Transition Detection  
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.  
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  
AD0 and AD2 Inputs Select from 16 Slave  
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.  
Addresses  
Low 0.6µA Standby Current  
-40°C to +125°C Temperature Range  
The MAX7324 uses two address inputs with four-level  
logic to allow 16 I2C slave addresses. The slave  
address also enables or disables internal 40kpullups  
in groups of four ports.
