PCA9554APW,118 Description

Short technical summary and product information.

The PCA9554APW,118 from NXP Semiconductors is a 16-pin TSSOP device providing 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications. It supports a wide operating supply voltage range of 2.3 V to 5.5 V and is 5 V tolerant on its I/Os. The device features 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.

 

Key features include an open-drain interrupt output activated when input states change, a power-on reset function, and a maximum clock frequency of 400 kHz. The PCA9554APW,118 is designed for applications requiring additional I/O, such as for ACPI power switches, sensors, push buttons, and LEDs. It is available in a 16-TSSOP surface mount package.

 

This IO Expander is suitable for various embedded systems and control applications where efficient I2C/SMBus communication is needed to expand the microcontroller's peripheral capabilities. Its robust design and standard interface make it a versatile component for adding digital I/O functionality.
