Notes about static electricity
Transistor of detector side in CMOS confi guration may be damaged by static electricity due to its minute
design.
When handling these devices, general countermeasure against static electricity should be taken to avoid
breakdown of devices or degradation of characteristics.

Design guide
In order to stabilize power supply line, we should certainly recommend to connect a by-pass capacitor of
0.01
μ
F or more between V
CC1
-GND and V
CC2
-GND near the device.
The detector which is used in this device, has parasitic diode between each pins and GND.
There are cases that miss operation or destruction possibly may be occurred if electric potential of any pin
becomes below GND level even for instant.
Therefore it shall be recommended to design the circuit that electric potential of any pin does not become
below GND level.
This product is not designed against irradiation and incorporates non-coherent LED.
