PCA9543B, PCA9543A, 2-channel I2C-bus switch

The PCA9543A/43B/43C is a bidirectional 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.
