CAT9534  
8-bit I²C and SMBus I/O Port with Interrupt  
FEATURES  
DESCRIPTION  
400kHz I²C bus compatible  
2.3V to 5.5V operation  
The CAT9534 is an 8-bit parallel input/output port  
expander 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  
8 I/O pins that default to inputs at power-up  
High drive capability  
The CAT9534 consists of an input port register, an  
output port register, a configuration register, a polarity  
inversion register and an I²C/SMBus-compatible serial  
interface.  
Individual I/O configuration  
Polarity inversion register  
Active low interrupt output  
Internal power-on reset  
No glitch on power-up  
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 CAT9534 input data by  
writing to the active-high polarity inversion register.  
Noise filter on SDA/SCL inputs  
Cascadable up to 8 devices  
Industrial temperature range  
The CAT9534 features an active low interrupt output  
which indicates to the system master that an input  
state has changed.  
RoHS-compliant 16-lead SOIC and TSSOP, and  
The device’s extended addressing capability allows up  
to 8 devices to share the same bus.  
16-pad TQFN (4 x 4mm) packages  
CAT9534 is offered in 16 pin SOIC, TSSOP and  
TQFN packages and operates over the full -40ºC to  
+85ºC industrial temperature range.  
APPLICATIONS  
White goods (dishwashers, washing machines)  
Handheld devices (cell phones, PDAs, digital  
cameras)  
For Ordering Information details, see page 15.  
Data Communications (routers, hubs and  
servers)
