Description
The DM164 is a LED current sink driver incorporating independent shift registers and data latches for grayscale PWM data (GD mode
1) and current adjustment data (D&G mode
1), 8x3-channels constant current circuitry with current value set by 3 external
resistors, 65,536 grayscale PWM function
