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 at low level, the latch circuit holds previous set of data
When LE terminal is at high level, the latch circuit refreshes new set of data from SDI chain
When OE 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 is at high level, all output terminals are switched OFF.
