PCA9538  
8-bit I2C-bus and SMBus low power I/O port with interrupt and  
reset  
Rev. 05 — 28 May 2009  
Product data sheet  
1. General description  
The PCA9538 is a 16-pin CMOS device that provides 8 bits of General Purpose parallel  
Input/Output (GPIO) expansion with interrupt and reset for I2C-bus/SMBus applications  
and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders.  
I/O expanders provide a simple solution when additional I/O is needed for ACPI power  
switches, sensors, push-buttons, LEDs, fans, etc.  
The PCA9538 consists 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 Input  
Port register can be inverted with the Polarity Inversion register. All registers can be read  
by the system master.  
The PCA9538 is identical to the PCA9554 except for the removal of the internal I/O pull-up  
resistor which greatly reduces power consumption when the I/Os are held LOW,  
replacement of A2 with RESET and different address range.  
The PCA9538 open-drain interrupt output (INT) 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. The RESET pin causes the same  
reset/initialization to occur without de-powering the device.  
Two hardware pins (A0 and A1) vary the fixed I2C-bus address and allow up to four  
devices to share the same I2C-bus/SMBus.  
2. Features  
I 8-bit I2C-bus GPIO with interrupt and reset  
I Operating power supply voltage range of 2.3 V to 5.5 V  
I 5 V tolerant I/Os  
I Polarity Inversion register  
I Active LOW interrupt output  
I Active LOW reset input  
I Low standby current  
I Noise filter on SCL/SDA inputs  
I No glitch on power-up  
I Internal power-on reset
