DESCRIPTION/ORDERING INFORMATION  
This 8-bit I/O expander for the two-line bidirectional bus (I2C) is designed for 2.3-V to 5.5-V VCC operation. The  
device provides general-purpose remote I/O expansion for most microcontroller families via the I2C interface  
[serial clock (SCL) and serial data (SDA)].  
The PCA9557 consists of one 8-bit configuration (input or output selection), input port, output port, and polarity  
inversion (active-high) registers. At power on, the I/Os are configured as inputs. However, 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 device outputs (latched) have high-current drive capability for directly driving LEDs. The device has low  
current consumption.
