PCA9554B; PCA9554C

Low-voltage 8-bit I

C-bus and SMBus low power I/O port with

interrupt, weak pull-up

Rev. 1 — 19 September 2012

Product data sheet

1. General description

The PCA9554B and PCA9554C are low-voltage 8-bit General Purpose Input/Output

(GPIO) expanders with interrupt for I

C-bus/SMBus applications. The only difference

between the PCA9554B and PCA9554C is their I

C fixed address allowing a larger

number of the same device on the I

C-bus with no chance of address conflict. NXP I/O

expanders provide a simple solution when additional I/Os are needed while keeping

interconnections to a minimum, for example, in ACPI power switches, sensors,

push buttons, LEDs, fan control, etc.

In addition to providing a flexible set of GPIOs, the wide V

range of 1.65 V to 5.5 V allow

the PCA9554B/PCA9554C to interface with next-generation microprocessors and

microcontrollers where supply levels are dropping down to conserve power.

The PCA9554B/PCA9554C contain a register set of 8-bit Configuration, Input, Output,

and Polarity Inversion registers.

The PCA9554B is a pin-to-pin replacement for the PCA9554, while the PCA9554C

replaces the PCA9554A. Both of these devices replace other industry-standard part

numbers. More fully-featured parts PCAL9554B and PCAL9554C are also available with

Agile I/O features. See the respective data sheet for more details.

The PCA9554B/PCA9554C open-drain interrupt (INT) 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.

INT can be connected to the interrupt input of a microcontroller. By sending an interrupt

signal on this line, the remote I/O can inform the microcontroller if there is incoming data

on its ports without having to communicate via the I

C-bus. Thus, the

PCA9554B/PCA9554C can remain a simple slave device.

The device outputs have 25 mA sink capabilities for directly driving LEDs while consuming

low device current.

The power-on reset sets the registers to their default values and initializes the device state

machine.

Three hardware pins (A0, A1, A2) select the fixed I

C-bus address and allow up to eight

devices to share the same I

C-bus/SMBus. The PCA9554B and PCA9554C differ only in

their base I

C-bus addresses permitting a total of 16 devices on the I

C-bus, minimizing

the chance for address conflict, even in the most complex system.
