FUNCTION
Ground
Serial-Data Input. Data is loaded into the internal 8-bit shift register on CLK’s rising edge.
Serial-Clock Input. Data is loaded into the internal 8-bit shift register on CLK’s rising edge.
4
LE
Load-Enable Input. Data is loaded transparently from the internal shift register to the output latch while
LE is high. Data is latched into the output latch on LE's falling edge, and retained while LE is low.
5–12
OUT0–OUT7
LED Driver Outputs. OUT0–OUT7 are open-drain, constant-current sinking outputs rated to 5.5V.
13
OE
Output-Enable Input. High forces outputs OUT0–OUT7 to high impedance, without altering the contents
of the output latches. Low enables outputs OUT0–OUT7 to follow the state of the output latches.

V+
Serial-Data Output. Data is clocked out of the 8-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.
Exposed pad on package underside. Connect to GND.
