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 terminal is low level, the latch circuit holds previous set of data.
When LE terminal is high level, the latch circuit refreshes new set of data from SDI chain.
When
latch circuits, either ‘1’ for ON or ‘0’ for OFF.
