Supply voltage terminal.
Input terminal of a data shift register. Data for R8 should be shifted in first, and then the data
for G8 followed.
Input terminal of a clock for shift register. Data is sampled at the rising edge of CLK.
Input terminal of data strobe. Data is latched when LTH is low. And data on shift register goes
through when LTH is high.
Input terminal of output enable (active low), all outputs are off when EN is high.
Constant current output terminals (Bank G).
Constant current output terminals (Bank R).
Ground terminals.
Input terminal of an external resistor (Bank G). The current flows through the resistor from
GRES to ground will be the (Bank G) reference base current of output sink current.
Input terminal of an external resistor (Bank R).
