WHY ACTIVE LOW PINS

Hi,

Open-collector and open-drain outputs are simpler to implement than a push-pull driver, the high impedance (when 'off') output allows it to be directly connected to other signals that may go high or low, thus it can also be used as an input.

Active low is always easier to realise in any logic family. And no ambiguity in the logic level.
