Notes: * Non connection regarding HA12229F.
1. Each pins are on pulled down with 100 kΩ internal resistor.
Therefore, it will be low-level when each pins are open.
2. Over shoot level and under shoot level of input signal must be the standardized.
(High: VCC, Low: –0.2 V)
3. Reducing pop noise is so much better for 10 kΩ to 22 kΩ resisitor and 1 µF to 22 µF capacitor
