Be sure to leave pin 40 open because it is connected to the lead frame.
Be sure to use all the Voo1, Vovz, Vssi, and Vssz pins. Keep the Vss: and Vssz pins at the same
voltage level.
. Supply power to Von, logic inputs, and Vooz in this order to protect the device from
destruction due to latch up. Turn off power in the reverse order.
Observe these power sequences even during a transition period.
Since uPD16306B have a CMOS structure, be careful about electrical static destruction.
