Description: 
This module is based on TCA9546A that is a quad bidirectional translation switch controlled via the I2C bus. The SCL/SDA upstream pair fans out to four downstream pairs of channels. Any individual SCn/SDn channel or combination of channels can be selected, determined by the contents of the programmable control register.
An active-low reset (RESET) input allows the TCA9546A to recover from a situation in which one of the downstream I2C buses is stuck in a low state. Pulling RESET low resets the I2C state machine and causes all the channels to be deselected, as does the internal power-on reset function.
