3. Operating Mode Control
HA12163 series provide fully electronic switching circuits. And each operating mode control are
controlled by parallel data (DC voltage).

Notes: 1. Each pins are on pulled down with 100 k
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: 5.3 V,
Low: –0.2 V)
3. When connecting microcomputer or Logic-IC with HA12163 series directly, there is apprehension
of rush-current under some transition timming of raising voltage or falling voltage at V
CC
ON/OFF.
On using, connect protective resistors of 10 to 22 k
to all the control pins. It is shown is test
circuit on this data sheet. And pins fixed to low level should be preferably open.
4. Pay attention not to make digital GND voltage lower than GND voltage.
