Serial data output to the following DIN of next driver IC
DOUT
Output enable terminal
When OE is low, the output drivers are enabled; when OE is high, all
output drivers are turned off
OEB
Constant current output terminals
IOUT[0:15]
Serial data is transferred to the output latch when STOBE is high. The
data is latched when STROBE goes low
STROBE
Clock input terminal for data shift to up-edge
CLK
Serial data input terminal for shift register
