Manufacturer: Nexperia

Overview: NCA9547A-Q100 8-channel I²C-bus multiplexer with reset Rev. 1 — 20 August 2025 Product data sheet 1.

General Description

The NCA9547-Q100 is an octal bidirectional translating multiplexer controlled by the I²C-bus.

The SCL/ SDA upstream pair fans out to eight downstream pairs, or channels.

Only one SCn/SDn channel can be selected at a time, determined by the contents of the programmable control register.
