Characteristics
The operating ranges must be maintained 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.
