5.5 Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused active low inputs should be tied to OVDD. Unused active high inputs should be connected to
GND. All no-connect (NC) signals must remain unconnected.
Power and ground connections must be made to all external VDD, OVDD, AVDD, and GND pins of the 750GX.
