PCA9555HF118 Description

Short technical summary and product information.

The PCA9555HF118 is a 16-bit General Purpose Parallel Input/Output (GPIO) expander from NXP Semiconductors, designed for seamless integration into I2C-bus and SMBus systems. This CMOS device offers enhanced features including higher drive capability, 5 V I/O tolerance, and lower supply current, making it suitable for applications requiring additional I/O for components like ACPI power switches, sensors, push buttons, and LEDs.

 

The PCA9555HF118 features two 8-bit configuration registers for selecting input or output modes, along with input, output, and polarity inversion registers. It supports a clock frequency range of 0 Hz to 400 kHz and includes an active-low interrupt output that signals changes in input states. The device operates within a supply voltage range of 2.3 V to 5.5 V and provides robust ESD protection exceeding 2000 V HBM.

 

With its flexible I/O configuration and compatibility with I2C-bus/SMBus, the PCA9555HF118 is an effective solution for expanding I/O capabilities in embedded systems. It is available in various packages, including DIP, SO, SSOP, TSSOP, HVQFN, and HWQFN, facilitating integration into diverse PCB designs.
