Pin No.
Pin nmae
Function
Equivalent circuit
Stabilized 5V system and 8V system power supply outputs.
The on/off state of these systems is controlled by the serial
data.
Application examples
13
CN2
Pin 13: Insert a capacitor of about 1
μF between this pin and
pin 14 to improve the TAPE8V ripple rejection.
This pin controls the pin 14 output voltage. Set this pin to
about 7V by inserting a resistor between this pin and ground if
impulse noise from the Dolby IC occurs in cranking mode.
14
TAPT8V (8V, 30mA)
Pin 14: TAPE8V, Cassette tape etc.
15
ACC5V (5V, 100mA)
Pin 15: ACC5V, digital system 5V power supply
16
RD8V (8V, 150mA)
Pin 16: RD8V, Radio etc.
17
CD5V (5V, 300mA)
Pin 17: CD5V, CD player etc.
18
FM8V (8V, 100mA)
Pin 18: FM8V power supply for use with a band switch.
19
COM8V (8V, 200mA)
Pin 19: COM8V power supply for an electronic volume/tone
control circuit.
*: Note that the total Pd must not exceed the IC rating.

The serial data received over this serial interface controls the
outputs other than COM10V and VDD5V. It also controls the
on/off state of P1 to P4.

STBY
Controls the running/stopped state of this IC.
When low, only VDD5V operates. All other circuits are
stopped.
When high, only COM10V and VDD5V operate
unconditionally. All other outputs are controlled by the serial
data.
