Pin Function Grouping


Arranged the symbol as requested: Channel A/B inputs left, outputs right, V+ top, and V− bottom.
Assign a Terminal Order from 1 to 10, starting with Power. Power should be Terminal Order 1, and Ground should be last, Terminal Order 10. For Orientation, set Power to "Top" and Ground to "Bottom." For the remaining sections/groups, you may decide the Terminal Order and Orientation yourself. For Orientation, distribute them between "Left" and "Right" — don't put everything on one side. Each group/section should have a different orientation.
This part has 8 terminals, not 10, and no dedicated Ground pin—V− is the negative supply, not necessarily GND.
Should I:
  1. Assign orders 1–8, with V+ = 1 (Top) and V− = 8 (Bottom); or
  2. Use orders 1–10 with gaps, treating V− as the last terminal (10) without relabeling it Ground?
Use option 1: assign Terminal Orders 1–8, with V+ first and V− last.
Assigned Terminal Orders 1–8:
  • V+ = 1, Top
  • Channel A = 2–4, Left/Right
  • Channel B = 5–7, Right/Left
  • V− = 8, Bottom
