CAT9534/D
CAT9534
8-bit I2C and SMBus I/O Port
with Interrupt
Description
The CAT9534 is an 8bit 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.
The CAT9534 consists of an input port register, an output port
register, a configuration register, a polarity inversion register and an
I2C/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
CAT9534 input data by writing to the activehigh polarity inversion
register.
The CAT9534 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.
CAT9534 is offered in 16 pin SOIC, TSSOP and TQFN packages
and operates over the full 40
°C to +85°C industrial temperature
range.
