Output pin of the internal constant-voltage circuit. Connect decoupling capacitor. Leakage input signal does not continue. Leakage is detected and SCR turn on. In these cases, this IC will be restored to the initial condition after a predetermined time. Connect capacitor that determines restore time. Pin for connecting capacitor that integrates signal output from discriminator of leak-signal input level. Pin for connecting capacitor to eliminate noise. Pin for connecting capacitor that sets delay time in case of using delay function. Output pin for driving a SCR. Pin for providing input reference level of leakage detection. About 2.4V appears. Other input pin of leakage detection. Output pin of operational amplifier. Pin for connecting capacitor that prevents abnormal oscillations. Connect capacitor across IC at pins 11 and 12. Negative input pins of operational amplifier Pin for connecting capacitor that prevents noise from causing malfunction. Connect capacitors across IC at pins 13 and 14 and across IC at pins 15 and 14.
