APPLICATION CIRCUIT
Notes: *1. The application circuit indicates a circuit by which fluorescent display tube filaments are ac driven
using a heater transformer. Contact fluorescent display tube manufacturers for the methods and
circuits of driving fluorescent display tube filaments.
*2. Keep the wires between the OSC0 pin and the crystal or ceramic resonator as short as possible to avoid
generating noise.
*3 For oscillation capacitor values, refer to data of the crystal or ceramic resonator used.
