IS31IO7325

MULTI-FUNCTION I/O DRIVER

January 2014

GENERAL DESCRIPTION

FEATURES

The IS31IO7325 2-wire serial-interfaced peripheral

features 16 I/O ports. Ports are divided into eight push

pull I/Os and eight open-drain I/Os and transition

detection.



400kHz I²C serial interface

2.4V to 5.5V operation

8 push-pull I/O ports

8 open-drain I/O ports, rated to 20mA sink current

at 0.22V headroom

Selectable I/O port power-up default logic states

INTB output alerts change on inputs

Low 0.3μA (Typ.) standby current

Any of the 16 I/O ports can be configured as an input

or an output. All I/O ports configured as inputs are

continuously monitored for state changes (transition

detection). State changes are indicated by the INTB

output. The interrupt is latched, allowing detection of

transient changes. When the IS31IO7325 is

subsequently read through the serial interface, any

pending interrupt is cleared.



-40°C ~ +125°C temperature range

APPLICATIONS

The open-drain outputs are rated to sink 20mA at

0.22V headroom, and are capable of driving LEDs.

The RSTB input clears the serial interface, terminating

any I²C communication to or from the IS31IO7325. The

IS31IO7325 uses two address inputs to allow 4 I²C

slave addresses. The slave address also determines

the power-up logic state for the I/O ports.

TYPICAL APPLICATION CIRCUIT

Figure 1 Typical Application Circuit

Note:

V_Battery: 2.4V~5.5V, 2.8V is recommended.

V_DD: 1.4V~5.5V, V_DD≤ V_Battery, 2.8V is recommended.

V_DDshould be turned off when system power off because OD ports are open default.

V_DD= V_Batteryis forbidden.
