When the load you're driving goes beyond \$V_\$.CMOS totem-poles are more symmetrical, and don't suffer from this. So don't use them when you need to both source and sink current. TTL totem-poles are highly asymmetrical: they can hardly source current, typically 0.4mA versus 16mA when sinking.Always use open collector/open drain drivers for wired AND. If one output is high and the other low you get a short. You can't use totem-poles for wired AND (often called wired OR, but most often they're ANDs).
