NCA6416 Description
The NCA6416 is a versatile 16-bit general-purpose I/ O expander designed for microcontrollers that need additional I/O pins. It municates via an I²C-bus interface, making it ideal for applications with minimal space and wiring, such as battery-powered devices using sensors, keypads, push buttons or LED control for managing LED brightness.
