CAT9555

16-bit I²C and SMBus I/O Port with Interrupt

FEATURES

DESCRIPTION

400kHz I²C bus compatible

The CAT9555 is a CMOS device that provides 16-bit

parallel input/output port expansion for I²C and SMBus

compatible applications. These I/O expanders provide

a simple solution in applications where additional I/Os

are needed: sensors, power switches, LEDs,

pushbuttons, and fans.

2.3V to 5.5V operation

Low stand-by current

5V tolerant I/Os

16 I/O pins that default to inputs at power-up

High drive capability

Individual I/O configuration

Polarity inversion register

Active low interrupt output

Internal power-on reset

No glitch on power-up

The CAT9555 consists of two 8-bit Configuration ports

(input or output), Input, Output and Polarity inversion

registers, and an I²C/SMBus-compatible serial interface.

Any of the sixteen I/Os can be configured as an input

or output by writing to the configuration register. The

system master can invert the CAT9555 input data by

writing to the active-high polarity inversion register.

Noise filter on SDA/SCL inputs

Cascadable up to 8 devices

Industrial temperature range

The CAT9555 features an active low interrupt output

which indicates to the system master that an input

state has changed.

RoHS-compliant 24-lead SOIC and TSSOP, and

24-pad TQFN (4 x 4mm) packages

The three address input pins provide the device's

extended addressing capability and allow up to eight

devices to share the same bus. The fixed part of the

I²C slave address is the same as the CAT9554,

allowing up to eight of these devices in any

combination to be connected on the same bus.

APPLICATIONS

White goods (dishwashers, washing machines)

Handheld devices (cell phones, PDAs, digital

cameras)

Data Communications (routers, hubs and servers)
