1. In Figure 9, When R3111xxxxC is used, and if an impedance is connected between Voltage Supplier
and the VDD Pin of R3111xxxxC Series, the operation might be unstable by cross conduction current at
detection.
When R3111xxxxA/B is used in Figure 9, if the value of R is set excessively large, voltage drop may
occur caused by supply current of IC itself and Detector threshold may vary.
2. Wiring as shown in Figure 10 may cause the oscillation in both output types of R3111 Series.
