PCA9554D,118 Description

Short technical summary and product information.

The PCA9554D,118 from NXP Semiconductors is an 8-bit General Purpose parallel Input/Output (GPIO) expansion device designed for I2C-bus/SMBus applications. It offers enhanced features such as higher drive capability, 5V I/O tolerance, and individual I/O configuration.

 

This I/O expander operates with a supply voltage range of 2.3V to 5.5V and supports a clock frequency up to 400 kHz. It includes an 8-bit Configuration register for input/output selection, an Input Port register, an Output Port register, and a Polarity Inversion register. The device features an open-drain interrupt output that activates when an input state changes, signaling the system master.

 

Designed for surface mount, the PCA9554D,118 comes in a 16-SOIC package. Its operating temperature range is -40°C to 85°C. This component is suitable for applications requiring additional I/O for sensors, push buttons, LEDs, and fans.
