PI4MSD5V9540B - DIODES

PI4MSD5V9540B 2-Channel I2C Bus Switch

The PI4MSD5V9540B 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. A power-on reset function puts the registers in their default state an.
