Precautions for Use
(1) This device is designed to be used under the condition of I
F
= 20mA
(2) It is recommended that a by-pass capacitor of more than 0.01
μ
F be added
between V
CC
and GND near the device in order to stabilize power supply line.
(3) As for other general cautions, refer to the chapter “Precautions for Use”.
