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.
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.
LED Driver Outputs. OUT0–OUT7 are open-drain, constant-current sinking outputs rated to 5.5V.
