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 CLK signal.
When LE/DM1 terminal is low level, the latch circuits hold previous set of data
When LE/DM1 terminal is high level, the latch circuits refresh new set of data from SDI
chain.
When OE/DM2 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/DM2 terminal is at high level, all output terminals will be switched OFF.
