Serial-Data Input. Data is loaded into the internal 16-bit shift register on CLK’s rising edge.
Serial-Clock Input. Data is loaded into the internal 16-bit shift register on CLK’s rising edge.
Load-Enable Input. Data is loaded transparently from the internal shift register(s) to the output latch(es)
while LE is high. Data is latched into the output latch(es) on LE’s falling edge, and retained while LE is
low.
LED Driver Outputs. OUT0 to OUT15 are open-drain, constant-current-sinking outputs rated to 5.5V.
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.
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
Positive Supply Voltage. Bypass V+ to GND with a 0.1µF ceramic capacitor.
