Destroyer hydrophones

Do destroyers has passive sonar (hydrophones) or do they only have active? Do I need to assume that if I'm at periscope depth and can hear them, then they can hear me as well? Or is it the same situation for the destroyers as when I am surfaced and can't use my hydrophones? If they do have hydrophones, are they as good as mine? Like I said I usually try to keep it quiet if I have any destroyers in my sonar range, but I am wondering if I am being too cautious? Yet they must have some hydrophone capabilities, because they can find you when you are close to them and are underwater running at more than 2-3 knots?
