As VEE pin is joined the substrate of chip, there is the possibility of latch-up in such case that the other pin is

supplied a voltage and VEE pin is open.

Therefore please use as VEE 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 100kΩ 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.

(High: Less than VCC, Low: More than –0.2V)
