Overview

PCA9849 4-channel ultra-low voltage, Fm+ I2C-bus multiplexer with reset Rev.
1 — 16 November 2015 Product data sheet 1.
General description The PCA9849 is an ultra-low voltage, quad bidirectional translating multiplexer controlled via the I2C-bus.
The SCL/SDA upstream pair fans out to four downstream pairs, or channels.
A single SCx/SDx channel can be selected, determined by the programmable control register.
This feature allows multiple devices with the same I2C-bus address to reside on the same bus.
