CAT9555  
16-bit I²C and SMBus I/O Port with Interrupt  
FEATURES  
DESCRIPTION  
„ 400kHz I²C bus compatible  
„ 2.3V to 5.5V operation  
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.  
„ Low stand-by current  
„ 5V tolerant I/Os  
„ 16 I/O pins that default to inputs at power-up  
„ High drive capability  
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.  
„ Individual I/O configuration  
„ Polarity inversion register  
„ Active low interrupt output  
„ Internal power-on reset  
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.  
„ No glitch on power-up  
„ 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)  
For Ordering Information details, see page 16.  
„ Data Communications (routers, hubs and servers)
