 User's Manual: sllu060.pdf / p.19 No6Pin IN1-, No7Pin IN1 +

User Manual: I saw a reference circuit of sllu060.pdf at P19.
The NC pin No8, No9, it is connected to VCC.

    Hello Asano-san,

    The datasheet has the correct pin assignment. It looks like the schematic shown in the User's Guide has the IN+ and IN- pins swapped. The layout images (and board images) show the correct assignments, though.

    The NC pins do not connect to anything in the device, so it is OK to either leave them unconnected (floating) or to tie them to a DC potential.

    Please let me know if you have any other questions.

    Regards,
    Max
