PCA9545A/45B/45C is an I2C bus expansion device, which can expand one I2C bus into four. After configuring the internal control registers, one or more downstream I2C buses can be selected to connect to the upstream I2C bus at the same time. The device has four interrupt inputs INT0 - INT3 and one interrupt output INT, which correspond to four downstream I2C buses and one upstream I2C bus respectively. The four interrupt inputs are ANDed to control the interrupt output INT status.
