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.
SCK
respective output will be OFF.
In order to ensure proper operations, an external resistor must be connected between the R-EXT and GND
pins and the logic power and a Toshiba-recommended capacitor should be connected between the VDD and
GND pins.
