5–20
OUT0–OUT15
LED Driver Outputs. OUT0 to OUT15 are open-drain, constant-current-sinking outputs rated to 28V.
21
OE
Output-Enable Input. High forces outputs OUT0 to OUT15 high impedance, without altering the contents
of the output latches. Low enables outputs OUT0 to OUT15 to follow the state of the output latches.

V+
Serial-Data Output. Data is clocked out of the 16-bit internal shift register to DOUT on CLK’s rising edge.
LED Current Setting. Connect SET to GND through a resistor (R
SET
) to set the maximum LED current.
Positive Supply Voltage. Bypass V+ to GND with a 0.1μF ceramic capacitor.
