FUNCTION

(QFN32)

(SDIP28, SSOP28)

V_DD

SIN

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.

CLK

LTH

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).

RESERVED Reserved pin for future.

SOUT

GRES

Output terminal of a data shift register.

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.

RRES

Input terminal of an external resistor (Bank R).
