Product Summary

The MC3334 is designed to use the signal from a reluctor type ignition pickup to produce a well controlled output from a power Darlington output transistor. The MC3334 high energy ignition circuit was designed to serve aftermarket Delco five–terminal ignition applications. This device, driving a high voltage Darlington transistor, offers an ignition system which optimizes spark energy at minimum power dissipation. The IC is pinned–out to permit thick film or printed circuit module design without any crossovers.
