Product Overview: PCA8575PW,112 by NXP Semiconductors

The PCA8575PW,112 is a robust, general-purpose I/O expander chip designed and manufactured by NXP Semiconductors. This device offers a simple solution for expanding bidirectional I/O lines via the two-wire I²C-bus (Inter-Integrated Circuit). The PCA8575PW,112 is particularly useful in applications where additional I/Os are needed or when microcontroller I/O resources are limited.

Key Features

• Expansive I/O Options: The device provides 16 additional I/O ports that can be configured as inputs or outputs, allowing for a versatile expansion of the host controller's capabilities.
• I²C-Bus Interface: It supports the standard (100 kHz), fast (400 kHz), and fast-plus (1 MHz) I²C-bus modes, offering flexibility in terms of communication speed and compatibility with various microcontrollers and processors.
• Low Standby Current: The PCA8575PW,112 is designed to have a low standby current, which is ideal for power-sensitive applications.
• Interrupt Output: An interrupt output is provided that can be connected to the interrupt logic of the microcontroller. This feature ensures immediate notification of I/O changes without requiring the host to continuously poll the expander.
• Wide Operating Voltage: The device operates across a wide voltage range from 2.3V to 5.5V, making it suitable for various logic levels and supply voltages.
