Notes to the characteristics
1. An input signal at pin 10 appears at pins 20 to 23 if the mute input (pin 18) is activated (V18-12 ≥ 2 V).
2. With mute (pin 18) ON both LEDs (pin 14 and 15) are switched OFF.
3. Pin 14 and 15 are also suitable as output switches to control TDA3810.
At LED OFF and I14, 15 ≤ 100 µA, then V14, 15-12 ≤ 200 mV.
