PCA9519
4-channel level translating I2C-bus/SMBus repeater
HIGH. It is important to note that any arbitration or clock stretching events require that the
LOW level on the port A bus at the input of the PCA9519 (VIL) is below VILc to be
recognized by the PCA9519 and then transmitted to the port B bus.
