Product data sheet  
4-bit I2C and SMBus low power I/O port  
with interrupt and reset  
PCA9537  
DESCRIPTION  
The PCA9537 is a 10-pin CMOS device that provide 4 bits of  
General Purpose parallel Input/Output (GPIO) expansion with  
2
interrupt and reset for I C/SMBus applications and was developed  
to enhance the Philips family of I@C I/O expanders. I/O expanders  
provides a simple solution when additional I/O is needed for ACPI  
power switches, sensors, pushbuttons, LEDs, fans, etc.  
The PCA9537 consists of a 4-bit Configuration register (Input or  
Output selection); 4-bit Input register, 4-bit Output register and a  
4-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 input port register can be inverted with the  
Polarity Inversion Register. All registers can be read by the system  
master.  
FEATURES  
2
• 4-bit I C GPIO with interrupt and reset  
• Operating power supply voltage range of 2.3 to 5.5 V  
• 5 V tolerant I/Os  
• Polarity inversion register  
The PCA9537 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. The RESET pin  
causes the same reset/initialization to occur without depowering the  
device.  
• Active LOW interrupt output  
• Active LOW reset input  
• Low stand-by current  
• Noise filter on SCL/SDA inputs  
• No glitch on power-up  
• Internal power-on reset  
2
The I C address is fixed and allows only one device on the same  
2
I C/SMBus.  
• 4 I/O pins which default to 4 inputs  
• 0 kHz to 400 kHz clock frequency  
• ESD protection exceeds 2000 V HBM per JESD22-A114,  
200 V MM per JESD22-A115 and 1000 V CDM per JESD22-C101  
• Latch-up testing is done to JEDEC Standard JESD78 which  
exceeds 100 mA  
• Offered in TSSOP10 package
