SLAT
The latch circuit is a leveled-latch circuit. Please exercise precaution as it is not triggered-latch circuit.
Keep the SLAT pin is set to “L” to enable the latch circuit to hold data. In addition, when the SLAT pin
is set to “H” the latch circuit does not hold data. The data will instead pass onto output.
When the OE pin is set to “L” the OUT0 to OUT15 output pins will go ON and OFF in response to
the data. In addition, when the OE pin is set to “H” all the output pins will be forced OFF regardless of
the data.
