If background disturbance light strikes a part on the package (other than the active area) of S6841, this may lower the allowable background light level. Use light-impervious tape to provide light-shielding over the shaded area of the package as shown below. Light-shielding is unnecessary for S8119. ACTIVE AREA LIGHT-SHIELDED AREA KPICC0067EA Light-shielded area (S6841) *4: H→L, L→H propagation delay time The optical system is adjusted so that the Vo terminal output becomes “Low” voltage when the switch shown in the circuit below is off. (S6841 is then measured with a signal light input of 1 µW/mm2 illuminance.)

If the input signal light exceeds this level, the propagation delay time may increase. 2 KPICC0062EA Photo IC for optical switch n Truth table ■ Block diagram CONSTANT VOLTAGE CIRCUIT 1 INV terminal: HIGH Input OUT output DSP output MRG output Light ON ON ON ON Light OFF OFF OFF OFF Vcc TO EACH CIRCUIT INV terminal: LOW Input OUT output DSP output MRG output Light ON OFF OFF ON Light OFF ON ON OFF COMPARATOR PRE-AMPLIFIER BUFFER PD COMPARATOR FOR MARGIN DISPLAY REF.
