I am using a TLV9064SIRTER quad opamp in my design. I'm not making use of the shutdown feature so the SHDN pins are tied directly to the positive rail in the PCB. The TLV9064IRTER comes in the same package but doesn't have the shutdown feature. The pins are NC in this device. Can I safely use this device in my existing PCB design or would the NC pins being connected to the positive rail cause any problems?
