PCA9554; PCA9554A

8-bit I

C-bus and SMBus I/O port with interrupt

Rev. 9 — 19 March 2013

Product data sheet

1. General description

The PCA9554 and PCA9554A are 16-pin CMOS devices that provide 8 bits of General

Purpose parallel Input/Output (GPIO) expansion for I

C-bus/SMBus applications and

were developed to enhance the NXP Semiconductors family of I

C-bus I/O expanders.

The improvements include higher drive capability, 5 V 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, push buttons, LEDs, fans, and so on.

The PCA9554/PCA9554A consist of an 8-bit Configuration register (Input or Output

selection); 8-bit Input Port register, 8-bit Output Port 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 Port or Output Port 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

C-bus address

compatible with the PCF8574 series, software changes are required due to the

enhancements and are discussed in

Application Note AN469.

The PCA9554/PCA9554A 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

C-bus address and allow up to eight

devices to share the same I

C-bus/SMBus. The PCA9554A is identical to the PCA9554

except that the fixed I

C-bus address is different allowing up to sixteen of these devices

(eight of each) on the same I

C-bus/SMBus.
