PCA9544A General Description

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. Four inter.
