Pin Functions
1. Standby switch function (pin 1)
If a microcontroller output signal is applied directly, insert a resistor in series
and adjust the current to a level optimal for the drive capability of the
microcontroller.
2. Input pins (pins 6 and 7)
The input pin voltage is about 2VBE (1.4V).
The input pin impedance is about 30k
.
Although the recommended value for the input capacitor is 1
F, the starting time can be modified by changing the
value of this capacitor. (The time from the point a voltage is applied to the standby pin to the point sound is emitted.)

3. FILTER (decoupling) pin (pin 8)
The pin voltage is about 1/2 VCC.
The recommended value for the filter capacitor is 100
F.
The pulse noise that occurs when the standby pin is set low (power off) will be degraded if a value under 100
F is used.
