DESCRIPTION
The CAT9555 is a CMOS device that provides 16-bit
parallel input/output port expansion for I
2
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
2
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
2
C
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
s
White goods (dishwashers, washing machines)
s
Handheld devices (cell phones, PDAs, digital
cameras)
s
Data Communications (routers, hubs and
servers)
