Function
Ground terminal for control logic and current
sink
SDI
Serial-data input to the shift register
CLK
Clock input terminal for data shift on rising
edge
Data strobe input terminal
LE
Serial data is transferred to the output latch
when LE is high. The data is latched when
LE goes low.
OUT0 ~ OUT15 Constant current output terminals
Output enable terminal
OE
When (active) low, the output drivers are
enabled; when high, all output drivers are
turned OFF (blanked).
SDO
Serial-data output to the following SDI of
next driver IC
R-EXT
Input terminal used to connect an external
resistor for setting up output current for all
output channels
