Note: The latches circuit holds data when the LATCH terminal is Low. When the LATCH
terminal is at High level, latch circuit doesn’t hold the data, it passes from the input to the output.
When the ENABLE terminal is at Low level, output terminals OUT0 to OUT15 respond to the
data, either ON or OFF. When the ENABLE terminal is at High level, it switches off all the data
on the output terminal.
