s Precautions for Use
( 1) It is recommended that a by-pass capacitor of more than 0.01 µ F is added between VCC and
GND near the device in order to stabilize power supply line.
( 2) Transistor of detector side in bipolar configuration is apt to be affected by static electricity
for its minute design. When handling them, general counterplan against static electricity
should be taken to avoid breakdown of devices or degradation of characteristics.
( 3) As for other general cautions, refer to the chapter “ Precautions for Use ”.
