Warning: Latch circuit is leveled­latch circuit. Be careful because it is not triggered­latch circuit.
Note 2: The latches circuit holds data by pulling the LATCH terminal Low.
And, when LATCH terminal is a high­level, latch circuit doesn’t hold data, and it passes from the input to
the output.
When ENABLE terminal is a low­level, output terminal OUT0 to OUT7 respond to the data, and on
and off does.
Attention: This IC can be used in 3.3 V or 5.0 V. However, use the V_DD power supply and the input level in the same
voltage system.
