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

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.
