The NXP Semiconductors PCA9539BS,115 is a 16-bit General Purpose Input/Output (GPIO) expander designed for I2C-bus and SMBus applications. This device provides a simple solution for systems requiring additional I/O, suitable for applications like ACPI power switches, sensors, push buttons, LEDs, and fans.
Key features include 16 bits of I/O expansion, an interrupt output, and a power-on reset function. The device operates with a supply voltage range of 2.3V to 5.5V and supports a clock frequency of up to 400 kHz. The I/Os are 5V tolerant.
The PCA9539BS,115 is housed in a 24-HVQFN (4x4) package and is designed for surface mount installation. It offers flexibility with configurable input/output registers and polarity inversion capabilities, allowing for active HIGH or active LOW operation. The interrupt output is activated when an input state changes, signaling the system master to handle the event.
