1. Due to the SCR structure inherent in these devices, connecting any display terminal or the display voltage terminal to a voltage outside
2.
the power supply to the chip may cause destructive device latchup. The digital inputs should never be connected to a voltage less than
-0.3V below ground, but maybe connected to voltages above V
