Expandable 5-channel I2C hub

DESCRIPTION The PCA9518 is a BiCMOS integrated circuit intended for application in I2C and SMBus systems. While retaining all the operating modes and features of the I2C system, it permits extension of the I2C-bus by buffering both the data (SDA) and the clock (SCL) lines, thus enabling virtual
