Hi . I'm using STGAP2D SO-14 IC in custom project with custom board , and in datasheet i see pin8 specified as N.C. (not connected). Pin8 must be left floating for ic to function properly , or can it be connected to nearby pin7 (GND) ?  Is this pin internally not connected at all (dummy pin) ,or it's connected internally to something ? i'm using single layer pcb currently with pin8 not connected and ic functions properly,but i would like a clear answer about possibility /prohibition of this pin connection - datasheet doesn't explains that . Thanks in advance .

The datasheet says it's not connected which means the pin isn't connected, so you can use it as you see fit.

Thanks for answer , i saw this line in datasheet too . But a reference board evalstgap2dm for this ic has pin8 insulated ,not connected ,so i'm still unsure .If wording would be "No internal connection" ,then there would be no question at all .
