PCA9544ABS, PCA9544A Datasheet - NXP

PCA9544ABS 4-channel I2C-bus multiplexer

The PCA9544A is a 1-of-4 bidirectional translating multiplexer, controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four 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. Four interrup.
