OUTn = ON when Dn = H OUTn = OFF when Dn = L
Figure 7.
Latch and output enable terminals are level-sensitive and are not synchronized with rising or
falling edge of CLK signal.
When LE/DM1 terminal is low level, the latch circuit holds previous set of data.
When LE/DM1 terminal is high level, the latch circuit refreshes new set of data from SDI
chain.
When OE/DM2 terminal is at low level, the output terminals Out 0 to Out 15 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 are switched OFF.
