wo Motorola M0C3011 optically coupled triac drivers are used in series to overcome voltage limhation of single coupler when triggering triac connected to control 240-VAC load. Two 1-megohm resistors equalize voltage drops across couplers．－P.O'Neil, Applications of the MOC3011 Triac Driver, Motorola, Phoenix,AZ,1978,AN-780,p5.
