DESCRIPTION
The PCA9554 and PCA9554A are 16-pin CMOS devices that
provide 8 bits of General Purpose parallel Input/Output (GPIO)
expansion for I
2
C/SMBus applications and were developed to
enhance the Philips family of I C I/O expanders. The improvements
include higher drive capability, 5V I/O tolerance, lower supply
current, individual I/O configuration, 400 kHz clock frequency, and
smaller packaging. I/O expanders provide a simple solution when
additional I/O is needed for ACPI power switches, sensors,
pushbuttons, LEDs, fans, etc.
The PCA9554/54A consist of an 8-bit Configuration register (Input or
Output selection); 8-bit Input register, 8-bit Output register and an
8-bit Polarity inversion register (Active-HIGH or Active-LOW
operation). The system master can enable the I/Os as either inputs
or outputs by writing to the I/O configuration bits. The data for each
Input or Output is kept in the corresponding Input or Output register.
The polarity of the read register can be inverted with the Polarity
Inversion Register. All registers can be read by the system master.
Although pin to pin and I
2
C address compatible with the PCF8574
series, software changes are required due to the enhancements and
are discussed in Application Note AN469
The PCA9554/54A open-drain interrupt output is activated when any
input state differs from its corresponding input port register state and
is used to indicate to the system master that an input state has
changed. The power-on reset sets the registers to their default
values and initializes the device state machine.
Three hardware pins (A0, A1, A2) vary the fixed I
2
C address and
allow up to eight devices to share the same I
2
C/SMBus. The
PCA9554A is identical to the PCA9554 except that the fixed I
2
C
address is different allowing up to sixteen of these devices (eight of
each) on the same I
2
C/SMBus.
