DESCRIPTION/ORDERING INFORMATION  
This 16-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation. It  
provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface [serial clock  
(SCL), serial data (SDA)].  
The PCA9539 consists of two 8-bit Configuration (input or output selection), Input Port, Output Port, and Polarity  
Inversion (active-high or active-low operation) registers. At power-on, the I/Os are configured as inputs. 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.  
The system master can reset the PCA9539 in the event of a time-out or other improper operation by asserting a  
low in the RESET input. The power-on reset puts the registers in their default state and initializes the I2C/SMBus  
state machine. Asserting RESET causes the same reset/initialization to occur without depowering the part.  
The PCA9539 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.
