                                                                                                    PI4MSD5V9546ALEX is a quad bidirectional translating switch controlled via I2C bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or combination of channels can be selected, determined by the contents of the programmable control register. An active LOW reset input allows the PI4MSD5V9546A to recover from a situation where one of the downstream buses is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C bus stat machine and cause all the channels to be deselected as does the internal Power-On Reset (POR) function. The pass gates of the switches are constructed such that the VCC pin can be used to limit the maximum high voltage which is passed by the PI4MSD5V9546A. This allows the use of different bus voltages on each pair, so that 1.2V, 1.8V or 2.5V or 3.3V parts can communicate with 5V parts without any additional protection. External pull-up resistors pull the bus up to the desired voltage level for each channel.

                                                                                                    • 1-of-4 bidirectional translating multiplexer, I2C-bus interface logic, all I/O pins are 5V tolerant
