CAT9554, CAT9554A  
8-bit I2C and SMBus I/O Port  
with Interrupt  
Description  
The CAT9554 and CAT9554A are CMOS devices that provide 8bit  
2
parallel input/output port expansion for I C and SMBus compatible  
http://onsemi.com  
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 CAT9554/9554A consist of an input port register, an output port  
register, a configuration register, a polarity inversion register and an  
I C/SMBuscompatible serial interface.  
Any of the eight I/Os can be configured as an input or output by  
writing to the configuration register. The system master can invert the  
CAT9554/9554A input data by writing to the activehigh polarity  
inversion register.

The CAT9554/9554A features an active low interrupt output which  
indicates to the system master that an input state has changed.  
The device’s extended addressing capability allows up to 8 devices  
to share the same bus. The CAT9554A is identical to the CAT9554

except the fixed part of the I C slave address is different. This allows  
up to 16 of devices (eight CAT9554 and eight CAT9554A) to be  
connected on the same bus.
