Note:
The latches circuit holds data when the LE terminal is Low.
1 When LE terminal is at High level, latch circuit hold the data it passes from the input to the
output.
2 When OE terminal is at Low level, output terminals OUT0 to OUT15 respond to the data,
either ON or OFF.
3 When OE terminal is at High level, it switches off all the data on the output terminal.
