HA12163 series provide fully electronic switching circuits. And each operating mode control are
controlled by parallel data (DC voltage).
2. Over shoot level and under shoot level of input signal must be the standardized (High: 5.3 V,
3. When connecting microcomputer or Logic-IC with HA12163 series directly, there is apprehension
4. Pay attention not to make digital GND voltage lower than GND voltage.
Therefore, it will be low-level when each pins are open.
