overshoot stresses, it is also advisable not to turn off the drivers and scan transistors simultaneously.
In order to obtain an ideal constant current output, a suitable output voltage is necessary. Users can get related
information about the minimum output voltage from the character table. Even under the same output current
condition, the minimum output voltage required for each part is different.
The resistor should be placed as close as possible to the
R-EXT
terminal to avoid the noise influence.
TIMING DIAGRAM
Note: The latches circuit holds data when LATCH terminal goes low voltage.
When LATCH terminal is a high voltage, latch circuit does not hold data, and it passes from the input to the
output.
When ENABLE terminal is a low voltage, output terminals respond to the data, and on and off does.
When ENABLE terminal is a high voltage, it closes with the output terminal regardless of the data.
