A bistable device comprises a thyristor having anode, cathode and gate electrodes and a transistor having emitter, collector and base electrodes, the emitter-collector path of the transistor being connected to the anode-cathode path of the thyristor. A first control input is connected to the gate of the thyristor for determining one stable state of the device and a second control input is connected to the base electrode of the transistor for determining the other stable state of the device. The first control input is connected through an amplifier to the gate of the transistor. |
