TCA9545A, Low Voltage 4-channel I2C and SMbus Switch

The TCA9545A 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 SCn/SDn channel or combination of channels can be selected, determined by the contents of the programmable control register.
