PCA9543 General Description

The PCA9543 is a bi-directional translating switch, controlled by the I2C-bus. The SCL/SDA upstream pair fans out to two downstream pairs, or channels. Any individual SCx/SDx channels or combination of channels can be selected, determined by the contents of the programmable control register. Two int.
