An input protect diode is connected from input detector 2's input (V
the voltage applied to V
Since the XC612 series are CMOS ICs, through current will flow when the IC's internal circuit switching operates
(during release and detect operations). Consequently, oscillation is liable to occur as a result of drops in voltage at
the through current's resistor (R
Since hysteresis exists during detect operations, oscillation is unlikely to occur.
