PD544A, Low Voltage 4-Channel I2C and SMBus Multiplexer

The PCA9544A is a 4-channel, bidirectional translating multiplexer controlled via the I2C bus.

The SCL/SDA upstream pair fans out to four downstream pairs, or channels.

One SCL/SDA pair can be selected at a time, and this is determined by the contents of the programmable control register.
