More Information

The PCA9545A 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. Four interrupt inputs ( INT3– INT0), one for each of the downstream pairs, are provided. One interrupt ( INT) output acts as an AND of the four interrupt inputs.
