All outputs ( OUT0 to OUT7 ) are disabled when the ENABLE terminal is driven High, and
enabled when it is driven Low.
Serial data output terminal. Serial data is clocked out on the falling edge of CLOCK.
An external resistor is connected between this terminal and ground. OUT0 to OUT7 are adjusted
to the same current value.
