The invention provides a circuit arrangement for scalable output drivers, symmetrically arranged driver transistor groups (504) being provided which each have transistor pairs (104, 105) having the same transistor line width (201). If there are m different driver transistor groups (504) present, 2(n-1) different gradations result, thereby achieving good scalability. Furthermore, a transistor line width (201, B) that is simple to design is provided for all transistors (104, 105) of all driver transistor groups (504), thereby providing identical electrical properties with respect to an output terminal unit (101).
