You are likely to get different answers from different people. Some will say both feet have to be out of the box, otherwise the batter is still in the box. Personally, every other rule in the book with regard to any line on the field requires only 1 foot to be across to be considered beyond the boundary. Before a pitch, the batter must have both feet inside the batters box. If the batter hits the ball with 1 foot completely outside the batters box, they are out. If the pitcher has one foot completely outside the circle, they are not considered to be in the circle. If a defensive player puts 1 foot into dead ball territory, they are considered to be in dead ball territory, etc etc etc.
Per my viewpoint and what I have been taught, if 1 foot is completely outside the box and the batter makes contact with the batted ball, they are out.
