Texas Instruments TCA6416ARTWR I/O Expander

The TCA6416ARTWR is a robust I/O expander from Texas Instruments (TI) designed to provide additional I/O capabilities to microcontroller-based systems. It operates as a 16-bit I2C and SMBus I/O expander with interrupt output, making it an ideal choice for applications that require additional I/O ports without the need for increasing the number of microcontrollers or upgrading to larger, more expensive ones.

Key Features:

• Interface: The device supports I2C and SMBus interfaces, allowing for easy integration with most microcontrollers.
• Expandability: It offers 16 additional I/O ports, which can be configured as either inputs or outputs.
• Interrupt Output: An interrupt output signals the host microcontroller when an input state has changed, enhancing system responsiveness.
• Voltage Range: The TCA6416ARTWR operates over a wide voltage range of 1.65V to 5.5V, making it suitable for various logic levels and power supplies.
• Package: The device comes in a 24-pin TSSOP (Thin Shrink Small Outline Package), which is ideal for space-constrained applications.
• Power Consumption: With its low power consumption, it is well-suited for battery-powered and power-sensitive applications.
