Precautions for Operation
1. It is recommended that a capacitor of about 1000pF is added between C-terminal and GND in order to prevent
malfunction of C-terminal due to noise. In the case of capacitor added, rise of the detecting voltage is delayed.
Thus, use together a resistance of about 1kΩ set between Vcc and C-terminal.
The C-terminal rise time varies with the time constant of CR added. Make it clear before use.
2.
The light-detecting element used for this product is provided with a parasitic diode between each terminal and GND.
When a terminal happens to reach electric potential lower than GND potential even in a moment, malfunction
or rupture may result. Design the circuit so that each terminal will be kept at electric potential lower than the
GND potential at all times.
