I C Port Expander with 8 Push-Pull

and 8 Open-Drain I/Os

General Description

Features

♦ 400kHz I²C Serial Interface

♦ +1.71V to +5.5V Operation

♦ 8 Push-Pull Outputs

The MAX7325 2-wire serial-interfaced peripheral features

16 I/O ports. Ports are divided into eight push-pull out-

puts and eight I/Os with selectable internal pullups and

transition detection. Eight ports are push-pull outputs

and eight I/Os may be used as a logic input or an open-

drain output. Ports are overvoltage protected to +6V.

♦ 8 Open-Drain I/O Ports, Rated to 20mA Sink

Current

♦ I/O Ports are Overvoltage Protected to +6V

♦ Selectable I/O Port Power-Up Default Logic States

♦ Transient Changes are Latched, Allowing

All I/O ports configured as inputs are continuously mon-

itored for state changes (transition detection). State

changes are indicated by the INT output. The interrupt

is latched, allowing detection of transient changes.

When the MAX7325 is subsequently accessed through

the serial interface, any pending interrupt is cleared.

The open-drain outputs are rated to sink 20mA, and are

capable of driving LEDs. The RST input clears the serial

Detection Between Read Operations

♦ INT Output Alerts Change on Inputs

♦ AD0 and AD2 Inputs Select from 16 Slave

Addresses

♦ Low 0.6µA (typ) Standby Current

♦ -40°C to +125°C Temperature Range

interface, terminating any I C communication to or from

the MAX7325.

The MAX7325 uses two address inputs with four-level

logic to allow 16 I²C slave addresses. The slave

address also determines the power-up logic state for

the I/O ports, and enables or disables internal 40kΩ

pullups in groups of four ports.
