Note:

The operating ranges are required to ensure the normal operation of the device. Unused inputs and bus

inputs must be tied to either VCC or GND. Please connect both bus inputs and the bus outputs with VCC or

GND when the I/O of the bus terminal changes by the function. In this case, please note that the output is

not short-circuited.
