The PCA9539PW/Q900,118 from NXP Semiconductors is a 16-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus and SMBus applications. It provides a simple solution for systems requiring additional I/O for devices such as sensors, push buttons, and LEDs.
This device features two 8-bit configuration registers, allowing I/Os to be selected as either inputs or outputs. It includes an open-drain interrupt output that activates when an input state changes, signaling the system master. The PCA9539PW/Q900,118 operates with a supply voltage range of 2.3V to 5.5V and supports I2C-bus clock frequencies up to 400 kHz.
The expander is housed in a 24-TSSOP package and is designed for surface mounting. It supports 5V tolerant I/Os and includes a reset input pin. The device is suitable for applications needing expanded I/O capabilities in a compact form factor.
