When looking at an op amp from the bottom, the pin count orientation is:

• A. CCW
• B. Up
• C. CW
• D. Down

Answer: (C)

The way pin numbers appear changes with the view you use. Pin numbering is defined from the top view, starting near a marker and proceeding in a certain direction. When you flip the part to look from the bottom, that sequence is reversed, so the pins appear in a clockwise order. So, reading the pins as you see them from the bottom matches a clockwise progression around the body. This is why clockwise is the correct orientation for bottom-view pin counting. Remember to check which view your datasheet uses, because top-view and bottom-view conventions differ.
