I C Port Expander with Eight Inputs and

Maskable Transition Detection

General Description

Features

ꢀ 400kHz, +5.5V-Tolerant I²C Serial Interface

The MAX7319 2-wire serial-interfaced peripheral fea-

tures eight input ports with selectable internal pullups,

overvoltage protection to +6V, and transition detection

with interrupt output.

ꢀ +1.71V to +5.5V Operating Voltage

ꢀ Eight Input Ports with Maskable, Latching

Transition Detection

ꢀ Input Ports are Overvoltage Protected to +6V

All input ports are continuously monitored for state

changes (transition detection). Transitions are latched,

allowing detection of transient changes. Any combination

of inputs can be selected using the interrupt mask to

assert the INT output. When the MAX7319 is subsequently

accessed through the serial interface, any pending inter-

rupt is cleared.

ꢀ Transient Changes are Latched, Allowing

Detection Between Read Operations

ꢀ INT Output Alerts Change on Any Selection of

Inputs

The +5.5V tolerant RST input clears the serial interface,

terminating any I²C communication to or from the

MAX7319.

ꢀ AD0 and AD2 Inputs Select from 16 Slave

Addresses

ꢀ Low 0.6µA (typ) Standby Current

The MAX7319 uses two address inputs with four-level

logic to allow 16 I²C slave addresses. The slave

address also enables or disables internal 40kΩ pullups

in groups of four ports.

ꢀ -40°C to +125°C Operating Temperature Range

The MAX7319 supports hot insertion. All eight input

ports, the serial interface SDA, SCL, AD0, AD2, INT,

and RST remain high impedance in power-down (V+ =

0) with up to +6V asserted on them.
