OUTn = ON when Dn = H OUTn = OFF when Dn = L
Figure 7.
Latch and output enable are level sensitive and ARE NOT synchronized with rising-or-falling
edge of CALK signal.
When LE terminal is low level, the latch circuits hold previous set of data
When LE terminal is at high level, the latch circuits refresh new set of data from SDI chain.
When OE terminal is at low level, the output terminals - Out0 to Out15 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.
