(Note) Latches are level sensitive (not edge triggered).
LATCH-terminal = H level, latches become transparent; LATCH-terminal = L level, latches hold data.
ENABLE-terminal = H level, all outputs (OUT0~15) are off.
An external resistor is connected between R-EXT and GND for setting up the value of constant current.
SERIAL-OUT changes state on the rising edges of clock.
