PCA9554AD Description

Short technical summary and product information.

The PCA9554AD from Philips (now 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 operates within a supply voltage range of 2.3 V to 5.5 V and features 5 V tolerant I/Os.

 

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 supports a clock frequency of up to 400 kHz. Its open-drain interrupt output is activated when any input state differs from its corresponding Input Port register state, signaling a change to the system master.

 

The PCA9554AD is suitable for applications requiring additional I/O, such as for ACPI power switches, sensors, push buttons, and LEDs. It is available in various packages including SO16, SSOP16, SSOP20, TSSOP16, and HVQFN16.
