NCA6416-Q100 Low-voltage translating 16-bit I²C-bus/SMBus I/O expander Rev. 1 — 20 August 2025 Product data sheet 1. General description The NCA6416-Q100 is a versatile 16-bit generalpurpose I/O expander designed for microcontrollers that need additional I/O pins. It communicates 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. Nexperia's I/O expanders feature a dual power supply architecture with two inputs: VCCI and VCCP. This design enables seamless level translation, supporting mixed-voltage environments.
