CAT9554, CAT9554A  
8-bit I2C and SMBus I/O Port with Interrupt  
FEATURES  
DESCRIPTION  
I 400kHz I2C bus compatible*  
I 2.3V to 5.5V operation  
The CAT9554 and CAT9554A are CMOS devices that  
provide 8-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.  
I Low stand-by current  
I 5V tolerant I/Os  
I 8 I/O pins that default to inputs at power-up  
I High drive capability  
TheCAT9554/9554Aconsistofaninputportregister,an  
output port register, a configuration register, a polarity  
inversion register and an I2C/SMBus-compatible serial  
interface.  
I Individual I/O configuration  
I Polarity inversion register  
I Active low interrupt output  
I Internal power-on reset  
Any of the eight I/Os can be configured as an input or  
outputbywritingtotheconfigurationregister.Thesystem  
master can invert the CAT9554/9554A input data by  
writing to the active-high polarity inversion register.  
I No glitch on power-up  
I Noise filter on SDA/SCL inputs  
I Cascadable up to 8 devices  
I Industrial temperature range  
The CAT9554/9554A features an active low interrupt  
outputwhichindicatestothesystemmasterthataninput  
state has changed.  
I RoHS-compliant 16-lead SOIC and TSSOP, and  
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 I2C  
slaveaddressisdifferent. Thisallowsupto16ofdevices  
(eight CAT9554 and eight CAT9554A) to be connected  
on the same bus.  
16-pad TQFN (4 x 4 mm) packages  
APPLICATIONS  
I White goods (dishwashers, washing machines)  
I Handheld devices (cell phones, PDAs, digital  
cameras)
