CAT9554, CAT9554A
8-bit I

C and SMBus I/O Port
with Interrupt
Description
The CAT9554 and CAT9554A are CMOS devices that provide 8−bit
parallel input/output port expansion for I
2
C 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 CAT9554/9554A consist of an input port register, an output port
register, a configuration register, a polarity inversion register and an
I
2
C/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
CAT9554/9554A input data by writing to the active−high 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
2
C slave address is different. This allows
up to 16 of devices (eight CAT9554 and eight CAT9554A) to be
connected on the same bus.
