DESCRIPTION

The CAT9555 is a CMOS device that provides 16-bit

parallel input/output port expansion for I

C 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.

The CAT9555 consists of two 8-bit Configuration ports

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

registers, and an I

C/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.

The CAT9555 features an active low interrupt output

which indicates to the system master that an input state

has changed.

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 I

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.

24-pad TQFN (4 x 4 mm) packages

APPLICATIONS

White goods (dishwashers, washing machines)

Handheld devices (cell phones, PDAs, digital

cameras)

Data Communications (routers, hubs and

servers)
