The PCA9554PW/Q900,118 is an 8-bit General Purpose parallel Input/Output (GPIO) expander designed for I2C-bus/SMBus applications by NXP Semiconductors. This CMOS device enhances I/O capabilities with features like 5 V I/O tolerance, individual I/O configuration, and a 400 kHz clock frequency.
Key specifications include an operating supply voltage range of 2.3 V to 5.5 V and an operating temperature range of -40°C to 85°C. The device provides 8 I/O pins, defaulting to inputs, and supports an interrupt output. It is available in a 16-TSSOP package suitable for surface mounting.
This I/O expander offers a simple solution for applications requiring additional I/O for components such as ACPI power switches, sensors, push buttons, LEDs, and fans. It includes an 8-bit Configuration register, Input Port register, Output Port register, and Polarity Inversion register, all accessible by the system master.
