PCA9555DB,118 Description

Short technical summary and product information.

The PCA9555DB,118 from NXP Semiconductors is a 16-bit General Purpose parallel Input/Output (GPIO) expander designed for I2C-bus/SMBus applications. It offers a wide operating supply voltage range of 2.3 V to 5.5 V and supports 5 V tolerant I/Os. This device features individual I/O configuration, allowing each pin to be set as either an input or an output.

 

Key electrical characteristics include a maximum clock frequency of 400 kHz and an interrupt output that is activated when an input state changes. The device provides 16 I/O pins, which default to inputs upon power-on reset. It is available in a 24-SSOP package, suitable for surface mount applications.

 

This I/O expander is useful for applications requiring additional I/O for components such as ACPI power switches, sensors, push buttons, LEDs, and fans. The PCA9555DB,118 is designed for reliable operation within an industrial temperature range of -40°C to 85°C.
