PCA9546ABS,118 Description
The PCA9546ABS,118 is a quad bidirectional translating switch controlled via the I2C-bus. The SCL/SDA upstream pair fans out to four downstream pairs, or channels. Any individual SCx/SDx channel or combination of media can be selected, determined by the contents of the programmable control register. An active LOW reset input allows the PCA9546ABS,118 to recover from a situation where one of the downstream I2C buses is stuck in a LOW state.
