LM139AQML-SP: How should I connect the LM139AQML-SP if it is not used

Wenchau Lo

Part Number: LM139AQML-SP

Hello,

I am only using 3 of the 4 comparator. How should I connect the one comparator that is not being used? Should I leave everything floating?

Thank you

Albert

See section 5.1.2 of the Application Design Guidelines for LM339, LM393, TL331 Family Comparators (which is linked to only from the non-space product page).
