PIN NAME
FUNCTION
GND
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
/OE

R-EXT
Output enable terminal
When (active) low, the output drivers are
enabled; when high, all output drivers are
turned OFF (blanked).
