PCA9554ABS,118 Description

Short technical summary and product information.

The PCA9554ABS,118 from NXP Semiconductors is a 16-pin CMOS device providing 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications. It supports a clock frequency of up to 400 kHz and operates within a supply voltage range of 2.3 V to 5.5 V.

 

This I/O expander includes an 8-bit Configuration register for input/output selection, an 8-bit Input Port register, an 8-bit Output Port register, and an 8-bit Polarity Inversion register. The device features an open-drain interrupt output that activates when an input state changes. It is available in a 16-HVQFN (4x4) package and is suitable for surface mount.

 

The PCA9554ABS,118 is designed for applications requiring additional I/O, such as for ACPI power switches, sensors, push buttons, LEDs, and fans. Its 5 V I/O tolerance and low supply current make it a versatile solution for various embedded systems.
