■ Precaution for use
(1) It is recommended that a by-pass capacitor of more than 0.01µF be 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.
