With no control signal at S, T 11 , T 32  are conducting and T 12 , T 31  are off. C 1  is completely discharged, C 2  having a small charge because of the conduction of T 32 . Owing to this charge, when an input signal appears at S, T 22  alone starts conducting, T 11  is turned off and T 12  starts conducting. The capacitors C 1 , C 2  acting as steering elements may be constituted by the capacitances of a diode or a transistor respectively, (Figs. 3-7, not shown) or by MOS capacitances. When transistors are used as steering elements instead of capacitors C 1 , C 2 , they may advantageously be monolithically integrated with the control transistors to form double emitter transistors (T 51 , Fig. 6, not shown). The resistances R 1 , R 2  may be repleced by transistors or FETs acting as resistors or constant current elements. A further transistor (T 71 , Fig. 8, not shown) coupling the bases of the switching and control transistors in each half may also be used for correct changeover of the bi-stable circuit. When a number of stages are to be connected in cascade or in a ring counter, to minimize uneven loading on the second half of the bi-stable, the resistors R 1 , R 2 , transistors T 31 , T 32  capacitors C 1 , C 2  are suitably designed asymmetrically.
