µPD4726
Notes 1. VDD and VSS output internally boosted voltages. Do not connect a load directly to these pins.
2. It is recommended that capacitors having a breakdown voltage of 20 V or higher be used as C1 through
C5. Inserting a bypass capacitor of 0.1 to 1 µF in between VCC and GND is also recommended.
3. Be sure to connect all the GND pins. Especially, make sure that pin 31 is connected; otherwise, the
µPD4726 will not operate normally. Be sure to leave the NC pins (pins 5 and 7) open.
4. The pull-up resistors for DIN1 through DIN4 and STBY and the pull-down resistor for EN are active resistors.
