Latch and output enable are level sensitive and are not synchronized with rising-or-falling
edge of CLK signal.
When LE terminal is low level, the latch circuit hold previous set of data.
When LE terminal is high level, the latch circuit refresh new set of data from SDI chain.
When OE terminal is at low level, the output terminal - Out 0 to Out 03 respond to data in the
latch circuits, either ‘1’ for ON or ‘0’ for OFF.
When OE terminal is at high level, all output terminals will be switched OFF.
