NC
This is a LD driver output terminal.
This is a supply terminal for a pulse driver output. In DC
luminescence mode, voltage which is bigger than V CC 1,
and flowing are available.
This is a switching terminal for DC/Pulse.
(Low: DC, High: Pulse)
This is a controlled current input terminal.
(Input resistance 330Ω)
NC
This is a power supply terminal of a controlled circuit
and driver output at DC luminescence. This can be
connected to V CC 2 to use as a common power supply.
NC
“Low” at pulse driver, and Iout output is ON.
