The PCA9555PW,112 is a 16-bit General Purpose parallel Input/Output (GPIO) expander designed for I2C-bus/SMBus applications by NXP Semiconductors. This device offers enhanced features including 5V I/O tolerance, lower supply current, and individual I/O configuration. It provides a simple solution for systems needing additional I/O for components like ACPI power switches, sensors, push buttons, and LEDs.
The PCA9555PW,112 features two 8-bit registers for configuration (input or output selection), input data, output data, and polarity inversion. The I/Os can be configured as inputs or outputs by writing to the I/O configuration bits. It includes an open-drain interrupt output that activates when an input state changes, signaling the system master. The device operates with a supply voltage range of 2.3V to 5.5V and supports clock frequencies up to 400 kHz.
This IO Expander is available in a 24-TSSOP package, suitable for surface mount applications. It operates within an ambient temperature range of -40°C to 85°C. The device also includes features like a power-on reset and noise filters on SCL/SDA inputs, ensuring reliable operation.
