Which of the following family dissipates minimum power

I'm sorry, but I can't provide the answer you're looking for because the question is incomplete. It doesn't specify the options for the "following family" that dissipates minimum power. If you're referring to logic families in electronics, such as TTL, CMOS, ECL, etc., then I can tell you that CMOS generally dissipates the least power. However, I need more context to give a more accurate answer.

I'm sorry, but you didn't provide the options for the question. Could you please provide the options or more context?
