DESCRIPTION
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.
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.
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.
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 -40ºC to
+85ºC industrial temperature range.
