PCA9542A Rev. 03 — 24 November 2008 www.DataSheet4U.com 2-channel I2C-bus multiplexer and interrupt logic Product data sheet 1. General description The PCA9542A is a 1-of-2 bidirectional translating multiplexer, controlled via the I2C-bus. The SCL/SDA upstream pair fans out to two SCx/SDx downstream pairs, or channels. Only one SCx/SDx channel is selected at a time, determined by the contents of the programmable control register. Two interrupt inputs, INT0 and INT1, one for each of the SCx/SD.
