Abstract
An output current unit comprises a cascode circuit having a first transistor connected between a voltage supply line and complementary outputs. Second and third transistors are controlled by inverter circuitry having parallel conducting paths between an output node and a ground line, the parallel conducting paths having different current carrying capacity with control circuitry to switch the stronger of the current carrying paths.
