F Circuit operation
(1) Timing chart
AUDIO 9V, MOTOR 14.7V, and COM 5V are output re-
gardless of MODE SW.
RADIO 5V rises when MODE SW is 1.4V (typical), and
CD 8V and CD 5V rise when MODE SW is 3.2V (typical).
(2) Estimate of allowable power dissipation
Except under transitional conditions, the power dissipa-
tion of this IC is 3W per unit at 25
_ C. See Fig. 3 for heat
reduction characteristics, including some cases where
heat sinks are used.
