Timing diagram Note: 1 Latch and output enable terminals are level-sensitive and are not synchronized with rising or falling edge of LE/DM1 signal. 2 When LE/DM1 terminal is low level, the latch circuit holds previous set of data. 3 When LE/DM1 terminal is high level, the latch circuit refreshes new set of data from SDI chain. 4 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. 5 When OE/DM2 terminal is at high level, all output terminals are switched OFF.
