TLV766-Q1: GND pin Floating

Part Number: TLV766-Q1
Other Parts Discussed in Thread: TPS745-Q1

We're looking fore p2p compatible with TPS73601(SON8 package) in the Motor drive application. 

It looks TLV766 is p2p but its pin 6 is GND pin, and TPS73601 is NC pin. Is it possible that the Pin6 left open or floating?
