When the CMOS gate circuit turns on and turns off, the circuit usually use the two-way SCR. Circuit (a) is the SCR conduction when the CMOS outputs the high level, the component model, resistance value and the high level value is as shown in table 1. Circuit (b) is the SCR conduction when the CMOS outputs the low level, the component model, resistance value and the high level value is as shown in table 2. Circuit (c) and circuit (d) are the SCR circuits which are drived by the negative gate current. Circuit (c) is the SCR which is triggered by the output high level, circuit (d) is the SCR which is triggered by the output low level.
