OUTn = ON when Dn = H OUTn = OFF when Dn = L
Figure 8.
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 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.
