Warning: Latch circuit is leveled-latch circuit. Be careful because it is not triggered-latch circuit.
Note 2:
The latches circuit holds data by pulling the LATCH terminal Low.
And, when LATCH terminal is a High level, latch circuit doesn’t hold data, and it passes from the input to
the output.
When ENABLE terminal is a Low level, output terminal OUT0 to OUT15 respond to the data, and on
and off does.
And, when ENABLE terminal is a High level, it offs with the output terminal regardless of the data.
