Pin Description
The external digital signal is entered. All of
RGB outputs become the black level when the
threshold value is about 0.7V for Vth1 and
about 1.8V for Vth2 and any one of RGB
exceeds Vth1 and become the white level only
for the output in which the input exceeds Vth2.
Connect to the ground when not using.

TRAP
1.0V
External trap pin.
Trap can be inserted into Y-signal by
connecting L and C in series to GND when
TRAP ON is set.

TEST1
-
Test pin.
Connect this pin normally to GND for use.

FBCOM
1.5V
Feedback circuit smoothing capacitor pin for
precharge output DC level control. Because of
high impedance, a capacitor with small
leakage is used.
