The TPT29546 is a 1:4 bidirectional translating I2C switch. The SCL/SDA upstream pair fans out to four downstream channels. Any single SCn/SDn channel or combination of channels can be selected, determined by the programmable control register. If one of the downstream I2C buses is stuck in a low state, then an active-low reset (RESET) input helps the TPT2954.
