Overview of PCA8575DB,118

The PCA8575DB,118 is a robust I/O expander from NXP Semiconductors designed to provide additional input/output (I/O) channels to microcontroller-based systems. This integrated circuit is ideal for applications where additional I/Os are necessary, and it utilizes the I²C-bus to interface with the host controller, which makes it a perfect choice for extending the I/O capability without adding extra microcontroller pins.

Key Features

• 16-bit I/O Expander: The device offers 16 additional I/O ports, which can be individually set to input or output.
• I²C Interface: It uses a two-wire I²C serial interface for communication, operating at a frequency of up to 400 kHz (Fast-mode) or up to 3400 kHz (High-speed mode).
• Interrupt Output: An interrupt output is provided that can be configured to reflect the input status, which is valuable for immediate notification of input changes without the need to continuously poll the expander.
• Wide Operating Voltage: The PCA8575DB,118 operates across a wide voltage range from 2.5V to 5.5V, making it suitable for various logic levels and power supplies.
• Low Standby Current: The device is optimized for low power consumption, with a low standby current that is ideal for power-sensitive applications.
