Introducing the PCF8575TS/1,118 I/O Expander from NXP Semiconductors

The PCF8575TS/1,118 is a robust I/O expander chip designed and manufactured by NXP Semiconductors, a leader in the field of advanced integrated circuits. This particular model is a pivotal component for designers looking to enhance the input/output capabilities of their microcontroller-based systems without incurring the cost and complexity of hardware redesign.

Key Features

• Expansive I/O Interface: The PCF8575TS/1,118 offers a substantial expansion, adding 16 additional I/O ports to your system. This is particularly useful for microcontroller projects that require a greater number of I/O lines than what is available on-board.
• Compatibility: It is designed to interface seamlessly with the standard I²C-bus, ensuring compatibility with a wide range of microcontrollers and processors that support this bus.
• Low Power Consumption: As with many of NXP's products, this I/O expander is optimized for low power consumption, making it ideal for battery-powered and energy-sensitive applications.
• Interrupt Feature: An interrupt output is provided, which can be configured to alert the host microcontroller of changes in input status without the need for constant polling, thus further reducing power consumption.
• Flexible Addressing: Up to eight PCF8575TS/1,118 devices can share the same I²C-bus, thanks to its three hardware address pins, allowing for a substantial expansion of up to 128 additional I/Os.

Applications

The versatility of the PCF8575TS/1,118 makes it an excellent choice for a wide array of applications. It is particularly well-suited for:

• Server motherboards
• Industrial control systems
• Home automation systems
• Robotics
• Portable electronics

Product Specifications

The PCF8575TS/1,118 comes in a slim TSSOP24 package, which is ideal for space-constrained applications.
