Note:
HA12206NT is designed to operate on split supply.
As V

Therefore please use as V

pin become the lowest voltage of low impedance all the time. When power
supply is thrown into this IC, that caution is necessary especially.
Operating Mode Control
HA12206NT provides fully electronic switching circuits. And each operating mode control is controlled by
parallel data (DC voltage).
Table 2 shows the control voltage of each control input pin.

1. Each pin is pulled down with 100k
internal resistor. 17 to 19 pins are low-level, 20 pin is mid-
level, when each pin is open.
2. Over shoot level and under shoot level of input signal must be the standardized.
