PCA9555HF,118 Description

Short technical summary and product information.

The PCA9555HF,118 from NXP Semiconductors is a 16-bit General Purpose parallel Input/Output (GPIO) expansion device designed for I2C-bus/SMBus applications. It offers higher drive capability, 5V I/O tolerance, and lower supply current compared to previous generations.

 

This I/O expander operates with a supply voltage range of 2.3V to 5.5V and supports a clock frequency of up to 400 kHz. It features 16 I/O pins that default to inputs, with individual I/O configuration options. The device includes a polarity inversion register and an active LOW interrupt output, which activates when an input state changes.

 

Packaged in a 24-HWQFN (4x4) with a surface mount type, the PCA9555HF,118 is suitable for various applications requiring additional I/O expansion, such as for ACPI power switches, sensors, push buttons, LEDs, and fans. The device also includes noise filtering on SCL/SDA inputs and has a power-on reset feature.
