MAX7323

I²C Port Expander with 4 Push-Pull

Outputs and 4 Open-Drain I/Os

General Description

Features

● 400kHz I C Serial Interface

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.

● +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 continuously

monitored for state changes (transition detection). State

changes are indicated by the open-drain INT output.

The interrupt is latched, allowing detection of transient

changes. When the MAX7323 is subsequently 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

The four push-pull and four open-drain outputs are rated

to sink 20mA and are capable of driving LEDs.

● AD0 and AD2 Inputs Select from 16 Slave Addresses

● Low 0.6µA (typ) Standby Current

The RST input clears the serial interface, terminating any

I C communication to or from the MAX7323.

The MAX7323 uses two address inputs with four-level

logic to allow 16 I C slave addresses. The slave 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.
