MC6820 external interface adapter can drive 4 dispersion gate 7400. The output signal is output by 7400 feeds back to MOC 3011 optical isolator. It controls three-terminal TRIAC, thenSCR cancontrol AC resistive load or AC inductive load. The second input end of NAND gate is connected to atransistorin 7400. The SCR will be turned on when AC input voltage crosses zero point. This way can last the life of incandescent longer and shorten the attackfrom surge current to three-terminal TRIAC.
