Each channel can be individually controlled with a simple serial communications protocol that is compatible with 3.
3-V or 5-V CMOS logic levels, depending on the operating VCC.
When the serial data buffer is loaded, a LAT rising edge transfers the data to the OUTn outputs.
The BLANK pin can be used to turn off all OUTn outputs during power-on and output data latching to prevent unwanted image displays during these times.
The constant-current value of all 16 channels is set by a single external resistor.
