Product Description

The PCA9539DWR is a 16-bit I/O Expander for the two-line bidirectional bus (I²C) is designed for 2.3 to 5.5V 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.
Open-drain active-low interrupt (INT)\ output
Active-Low Reset Input
Compatible with most microcontrollers
Polarity inversion register
Address by 2 hardware address pins for use of up to 4 devices
Latched outputs with high-current drive capability for directly driving LEDs
